+**********************************************************
+**This is not the repository you want to file issues in!**
+**********************************************************
+
+Note that a failing HTTP connection is almost certainly not caused by a bug in
+package:http.
+
+This package is a wrapper around the HttpClient from dart:io and HttpRequest
+from dart:html. Before filing a bug here verify that the issue is not surfaced
+when using those interfaces directly.
+
+https://api.dart.dev/stable/dart-io/HttpClient-class.html
+https://api.dart.dev/stable/dart-html/HttpRequest-class.html
+
+# Common problems:
+
+- A security policy prevents the connection.
+- Running in an emulator that does not have outside internet access.
+- Using Android and not requesting internet access in the manifest.
+  https://github.com/flutter/flutter/issues/29688
+
+None of these problems are influenced by the code in this repo.
+
+# Diagnosing:
+
+- Attempt the request outside of Dart, for instance in a browser or with `curl`.
+- Attempt the request with the dart:io or dart:html equivalent code paths.

+  works when using `dart:io` or `dart:html` directly.
+title: ''

+
+---
+
+Please describe the bug and how to reproduce it.
+
+Note that if the bug can also be reproduced when going through the interfaces provided by `dart:html` or `dart:io` directly the bug should be filed against the Dart SDK: https://github.com/dart-lang/sdk/issues
+
+A failure to make an HTTP request is more often a problem with the environment than with the client.

+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.

+[![package publisher](https://img.shields.io/pub/publisher/cronet_http.svg)](https://pub.dev/packages/cronet_http/publisher)
+
+An Android Flutter plugin that provides access to the
+[Cronet][] HTTP client.
+
+Cronet is available as part of [Google Play Services][]
+and as [a standalone embedded library][].
+
+This package depends on [Google Play Services][]
+for its [Cronet][] implementation.
+To use the embedded version of [Cronet][] without [Google Play Services][],
+see [Use embedded Cronet](#use-embedded-cronet).
+
+## Motivation
+
+Using [Cronet][], rather than the socket-based
+[dart:io HttpClient][] implementation, has several advantages:
+
+1. It automatically supports Android platform features such as HTTP proxies.
+2. It supports configurable caching.
+3. It supports more HTTP features such as HTTP/3.
+
+## Using
+
+The easiest way to use this library is via the high-level interface
+defined by [package:http Client][].
+
+This approach allows the same HTTP code to be used on all platforms, while
+still allowing platform-specific setup.
+
+```dart
+import 'package:cronet_http/cronet_http.dart';
+import 'package:http/http.dart';
+import 'package:http/io_client.dart';
+
+void main() async {
+  final Client httpClient;
+  if (Platform.isAndroid) {
+    final engine = CronetEngine.build(
+        cacheMode: CacheMode.memory,
+        cacheMaxSize: 2 * 1024 * 1024,
+        userAgent: 'Book Agent');
+    httpClient = CronetClient.fromCronetEngine(engine, closeEngine: true);
+  } else {
+    httpClient = IOClient(HttpClient()..userAgent = 'Book Agent');
+  }
+
+  final response = await client.get(
+    Uri.https(
+      'www.googleapis.com',
+      '/books/v1/volumes',
+      {'q': 'HTTP', 'maxResults': '40', 'printType': 'books'},
+    ),
+  );
+  httpClient.close();
+}
+```
+
+### Use embedded Cronet
+
+If you want your application to work without [Google Play Services][],
+you can instead depend on the `org.chromium.net:cronet-embedded` package
+by using `dart-define` to set `cronetHttpNoPlay` is set to `true`.
+
+For example:
+
+```
+flutter run --dart-define=cronetHttpNoPlay=true
+```
+
+To use the embedded version in `flutter test`:
+
+```
+flutter test --dart-define=cronetHttpNoPlay=true
+```

+## 2.0.2-wip
+
+* Upgrade to `package:objective_c` 4.0.
+
+## 2.0.1
+
+* Fix a [bug](https://github.com/dart-lang/http/issues/1398) where
+  `package:cupertino_http` only worked with iOS 17+. 
+
+## 2.0.0
+
+* The behavior of `CupertinoClient` and `CupertinoWebSocket` has not changed.
+* **Breaking:** `MutableURLRequest.httpBodyStream` now takes a `NSInputStream`
+  instead of a `Stream<List<int>>`.
+* **Breaking:** The following enums/classes previous defined by
+  `package:cupertino_http` are now imported from `package:objective_c`:
+    * `NSData`
+    * `NSError`
+    * `NSHTTPCookieAcceptPolicy`
+    * `NSMutableData`
+    * `NSURLRequestCachePolicy`
+    * `NSURLRequestNetworkServiceType`
+    * `NSURLSessionMultipathServiceType`
+    * `NSURLSessionResponseDisposition`
+    * `NSURLSessionTaskState`
+    * `NSURLSessionWebSocketCloseCode`
+    * `NSURLSessionWebSocketMessageType`
+* **Breaking:** `URLSession.dataTaskWithCompletionHandler` is no longer
+  supported for background sessions.
+
+## 1.5.1
+
+* Allow `1000` as a `code` argument in `CupertinoWebSocket.close`.
+* Fix a bug where the `Content-Length` header would not be set under certain
+  circumstances.
+
+## 1.5.0
+
+* Add integration to the
+  [DevTools Network View](https://docs.flutter.dev/tools/devtools/network).
+* Upgrade to `package:ffigen` 11.0.0.
+* Bring `WebSocket` behavior in line with the documentation by throwing
+  `WebSocketConnectionClosed` rather than `StateError` when attempting to send
+  data to or close an already closed `CupertinoWebSocket`.
+* Update minimum supported iOS/macOS versions to be in sync with the minimum
+  (best effort) supported for Flutter: iOS 12, macOS 10.14.
+* Eagerly free resources on `CupertinoClient.close()`.
+
+## 1.4.0
+
+* **Experimental** support for the `package:web_socket` `WebSocket` interface.
+
+## 1.3.0
+
+* Use `package:http_image_provider` in the example application.
+* Support `BaseResponseWithUrl`.
+
+## 1.2.0
+
+* Add support for setting additional http headers in
+  `URLSessionConfiguration`.
+
+## 1.1.0
+
+* Add websocket support to `cupertino_api`.
+* Add streaming upload support, i.e., if `CupertinoClient.send()` is called
+  with a `StreamedRequest` then the data will be sent to the server
+  incrementally.
+* Deprecate `Data.fromUint8List` in favor of `Data.fromList`, which accepts
+  any `List<int>`.
+* Disable additional analyses for generated Objective-C bindings to prevent
+  errors from `dart analyze`.
+* Throw `ClientException` when the `'Content-Length'` header is invalid.
+* Add support for configurable caching through
+  `URLSessionConfiguration.cache`.
+
+## 1.0.1
+
+* Remove experimental status from "Readme"
+
+## 1.0.0
+
+* Require Dart 3.0
+* Require Flutter 3.10.0
+
+## 0.1.2
+
+* Require Dart 2.19
+* Fix a [reference count race with forwarded delegates](https://github.com/dart-lang/http/issues/887).
+
+## 0.1.1
+
+* Add a `URLSession.sessionDescription` field.
+
+## 0.1.0
+
+* Restructure `package:cupertino_http` to offer a single `import`.
+
+## 0.0.11
+
+* Fix a bug where the images in the example would be loaded using `dart:io`
+  `HttpClient`.
+* `CupertinoClient` throws an exception if `send` is called after `close`.
+
+## 0.0.10
+
+* Fix [Use of multiple CupertinoClients can result in cancelled requests](https://github.com/dart-lang/http/issues/826)
+
+## 0.0.9
+
+* Add a more complete implementation for `URLSessionTask`:
+  * `priority` property - hint for host prioritization.
+  * `currentRequest` property - the current request for the task (will be
+    different than `originalRequest` in the face of redirects).
+  * `originalRequest` property - the original request for the task. 
+  * `error` property - an `Error` object if the request failed.
+  * `taskDescription` property - a developer-set description of the task.
+  * `countOfBytesExpectedToSend` property - the size of the body bytes that
+    will be sent.
+  * `countOfBytesSent` property - the number of body bytes sent in the request.
+  * `prefersIncrementalDelivery` property - whether to deliver the response
+    body in one chunk (if possible) or many.
+* Upgrade to ffigen ^7.2.0 and remove unnecessary casts.
+
+## 0.0.8
+
+* Make timeout and caching policy configurable on a per-request basis.
+
+## 0.0.7
+
+* Upgrade `ffi` dependency.
+
+## 0.0.6

+
+## Architecture
+
+![Architecture Diagram](./img/architecture.svg?raw=true)
+
+`package:cupertino_http` is organized into three components:
+1. [bindings](lib/src/native_cupertino_bindings.dart) generated by
+   [ffigen](https://pub.dev/packages/ffigen) to relevant
+   [Foundation framework](https://developer.apple.com/documentation/foundation)
+   functionality. Configured using [`ffigen.yaml`](ffigen.yaml).
+2. A [native helper library](src/) that fills gaps in the generated bindings.
+3. Dart source that provides a high-level interface to the
+   [Foundation framework](https://developer.apple.com/documentation/foundation)
+   [URL Loading System](https://developer.apple.com/documentation/foundation/url_loading_system).

+
+A macOS/iOS Flutter plugin that provides access to the
+[Foundation URL Loading System][].
+
+## Motivation
+
+Using the [Foundation URL Loading System][], rather than the socket-based
+[dart:io HttpClient][] implementation, has several advantages:
+
+1. It automatically supports iOS/macOS platform features such VPNs and HTTP
+   proxies. 
+2. It supports many more configuration options such as only allowing access
+   through WiFi and blocking cookies.
+3. It supports more HTTP features such as HTTP/3 and custom redirect handling.
+
+## Using
+
+The easiest way to use this library is via the high-level interface
+defined by [package:http Client][].
+
+This approach allows the same HTTP code to be used on all platforms, while
+still allowing platform-specific setup.
+
+```dart
+import 'package:cupertino_http/cupertino_http.dart';
+import 'package:http/http.dart';
+import 'package:http/io_client.dart';
+
+void main() async {
+  final Client httpClient;
+  if (Platform.isIOS || Platform.isMacOS) {
+    final config = URLSessionConfiguration.ephemeralSessionConfiguration()
+      ..cache = URLCache.withCapacity(memoryCapacity: 2 * 1024 * 1024)
+      ..httpAdditionalHeaders = {'User-Agent': 'Book Agent'};
+    httpClient = CupertinoClient.fromSessionConfiguration(config);
+  } else {
+    httpClient = IOClient(HttpClient()..userAgent = 'Book Agent');
+  }
+
+  final response = await client.get(Uri.https(
+      'www.googleapis.com',
+      '/books/v1/volumes',
+      {'q': 'HTTP', 'maxResults': '40', 'printType': 'books'}));
+}
+```
+
+[CupertinoWebSocket][] provides a [package:web_socket][] [WebSocket][]
+implementation.
+
+```dart
+import 'package:cupertino_http/cupertino_http.dart';
+import 'package:web_socket/web_socket.dart';
+
+void main() async {
+  final socket = await CupertinoWebSocket.connect(
+      Uri.parse('wss://ws.postman-echo.com/raw'));
+
+  socket.events.listen((e) async {
+    switch (e) {
+      case TextDataReceived(text: final text):
+        print('Received Text: $text');
+        await socket.close();
+      case BinaryDataReceived(data: final data):
+        print('Received Binary: $data');
+      case CloseReceived(code: final code, reason: final reason):
+        print('Connection to server closed: $code [$reason]');
+    }
+  });
+}
+```
+
+You can also use the [Foundation URL Loading System] API directly.
+
+```dart
+final url = Uri.https(
+    'www.googleapis.com',
+    '/books/v1/volumes',
+    {'q': 'HTTP', 'maxResults': '40', 'printType': 'books'});
+final session = URLSession.sharedSession();
+final task = session.dataTaskWithCompletionHandler(URLRequest.fromUrl(url),
+    (data, response, error) {
+  if (error == null && response!.statusCode == 200) {
+    print(data!.bytes);
+  }
+});
+task.resume();
+```

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

+/// An NSURLSessionDataTask receives the resource as a series of calls to
+/// the URLSession:dataTask:didReceiveData: delegate method.  This is type of
+/// task most commonly associated with retrieving objects for immediate parsing
+/// by the consumer.
+///
+/// An NSURLSessionUploadTask differs from an NSURLSessionDataTask
+/// in how its instance is constructed.  Upload tasks are explicitly created
+/// by referencing a file or data object to upload, or by utilizing the
+/// -URLSession:task:needNewBodyStream: delegate message to supply an upload
+/// body.
+///
+/// An NSURLSessionDownloadTask will directly write the response data to
+/// a temporary file.  When completed, the delegate is sent
+/// URLSession:downloadTask:didFinishDownloadingToURL: and given an opportunity
+/// to move this file to a permanent location in its sandboxed container, or to
+/// otherwise read the file. If canceled, an NSURLSessionDownloadTask can
+/// produce a data blob that can be used to resume a download at a later
+/// time.
+///
+/// Beginning with iOS 9 and Mac OS X 10.11, NSURLSessionStream is
+/// available as a task type.  This allows for direct TCP/IP connection
+/// to a given host and port with optional secure handshaking and
+/// navigation of proxies.  Data tasks may also be upgraded to a
+/// NSURLSessionStream task via the HTTP Upgrade: header and appropriate
+/// use of the pipelining option of NSURLSessionConfiguration.  See RFC
+/// 2817 and RFC 6455 for information about the Upgrade: header, and
+/// comments below on turning data tasks into stream tasks.
+///
+/// An NSURLSessionWebSocketTask is a task that allows clients to connect to servers supporting
+/// WebSocket. The task will perform the HTTP handshake to upgrade the connection
+/// and once the WebSocket handshake is successful, the client can read and write
+/// messages that will be framed using the WebSocket protocol by the framework.

If this method returns NO, the optional error is populated. This method is currently applicable only to URLs for file system resources. For other URL types, NO is returned. Symbol is present in iOS 4, but performs no operation.

+# flutter_http_example
+
+A Flutter sample app that illustrates how to configure and use
+[`package:http`](https://pub.dev/packages/http).
+
+## Goals for this sample
+
+* Provide you with example code for using `package:http` in Flutter,
+  including:
+
+    * configuration for multiple platforms.
+    * using `package:provider` to pass `Client`s through an application.
+    * writing tests using `MockClient`.
+
+## The important bits
+
+### `http_client_factory.dart`
+
+This library used to create `package:http` `Client`s when the app is run inside
+the Dart virtual machine, meaning all platforms except the web browser.
+
+### `http_client_factory_web.dart`
+
+This library used to create `package:http` `Client`s when the app is run inside
+a web browser.
+
+Web configuration must be done in a separate library because Dart code cannot
+import `dart:ffi` or `dart:io` when run in a web browser.
+
+### `main.dart`
+
+This library demonstrates how to:
+
+* import `http_client_factory.dart` or `http_client_factory_web.dart`,
+  depending on whether we are targeting the web browser or not.
+* share a `package:http` `Client` by using `package:provider`.
+* call `package:http` `Client` methods.
+
+### `widget_test.dart`
+
+This library demonstrates how to construct tests using `MockClient`.

+## 1.3.0-wip
+
+* Fixed unintended HTML tags in doc comments.
+* Switched `BrowserClient` to use Fetch API instead of `XMLHttpRequest`.
+
+## 1.2.2
+
+* Require package `web: '>=0.5.0 <2.0.0'`.
+
+## 1.2.1
+
+* Require Dart `^3.3`
+* Require `package:web` `^0.5.0`.
+
+## 1.2.0
+
+* Add `MockClient.pngResponse`, which makes it easier to fake image responses.
+* Added the ability to fetch the URL of the response through `BaseResponseWithUrl`.
+* Add the ability to get headers as a `Map<String, List<String>` to
+  `BaseResponse`.
+
+## 1.1.2
+
+* Allow `web: '>=0.3.0 <0.5.0'`.
+
+## 1.1.1
+
+* `BrowserClient` throws `ClientException` when the `'Content-Length'` header
+  is invalid.
+* `IOClient` trims trailing whitespace on header values.
+* Require Dart 3.2
+* Browser: support Wasm by using `package:web`.
+
+## 1.1.0
+
+* Add better error messages for `SocketException`s when using `IOClient`.
+* Make `StreamedRequest.sink` a `StreamSink`. This makes `request.sink.close()`
+  return a `Future` instead of `void`, but the returned future should _not_ be
+  awaited. The Future returned from `sink.close()` may only complete after the
+  request has been sent.
+
+## 1.0.0
+
+* Requires Dart 3.0 or later.
+* Add `base`, `final`, and `interface` modifiers to some classes.
+
+## 0.13.6
+
+* `BrowserClient` throws an exception if `send` is called after `close`.
+* If `no_default_http_client=true` is set in the environment then disk usage
+  is reduced in some circumstances.
+* Require Dart 2.19
+
+## 0.13.5
+
+* Allow async callbacks in RetryClient.
+* In `MockHttpClient` use the callback returned `Response.request` instead of
+  the argument value to give more control to the callback. This may be breaking
+  for callbacks which return incomplete Responses and relied on the default.
+
+## 0.13.4
+
+* Throw a more useful error when a client is used after it has been closed.
+* Require Dart 2.14.
+
+## 0.13.3
+
+* Validate that the `method` parameter of BaseRequest is a valid "token".
+
+## 0.13.2
+
+* Add `package:http/retry.dart` with `RetryClient`. This is the same
+  implementation as `package:http_retry` which will be discontinued.
+
+## 0.13.1
+
+* Fix code samples in `README` to pass a `Uri` instance.
+
+## 0.13.0
+
+* Migrate to null safety.
+* Add `const` constructor to `ByteStream`.
+* Migrate `BrowserClient` from `blob` to `arraybuffer`.
+* **Breaking** All APIs which previously allowed a `String` or `Uri` to be
+  passed now require a `Uri`.
+* **Breaking** Added a `body` and `encoding` argument to `Client.delete`. This
+  is only breaking for implementations which override that method.
+
+## 0.12.2
+
+* Fix error handler callback type for response stream errors to avoid masking
+  root causes.
+
+## 0.12.1
+
+* Add `IOStreamedResponse` which includes the ability to detach the socket.
+  When sending a request with an `IOClient` the response will be an
+  `IOStreamedResponse`.
+* Remove dependency on `package:async`.
+
+## 0.12.0+4
+
+* Fix a bug setting the `'content-type'` header in `MultipartRequest`.
+
+## 0.12.0+3
+
+* Documentation fixes.
+
+## 0.12.0+2
+
+* Documentation fixes.
+
+## 0.12.0
+
+### New Features
+
+* The regular `Client` factory constructor is now usable anywhere that `dart:io`
+  or `dart:html` are available, and will give you an `IoClient` or
+  `BrowserClient` respectively.
+* The `package:http/http.dart` import is now safe to use on the web (or
+  anywhere that either `dart:io` or `dart:html` are available).
+
+### Breaking Changes
+
+* In order to use or reference the `IoClient` directly, you will need to import
+  the new `package:http/io_client.dart` import. This is typically only necessary
+  if you are passing a custom `HttpClient` instance to the constructor, in which
+  case you are already giving up support for web.
+
+## 0.11.3+17
+
+* Use new Dart 2 constant names. This branch is only for allowing existing
+  code to keep running under Dart 2.
+
+## 0.11.3+16
+
+* Stop depending on the `stack_trace` package.
+
+## 0.11.3+15
+
+* Declare support for `async` 2.0.0.
+
+## 0.11.3+14
+
+* Remove single quote ("'" - ASCII 39) from boundary characters.
+  Causes issues with Google Cloud Storage.
+
+## 0.11.3+13
+
+* remove boundary characters that package:http_parser cannot parse.
+
+## 0.11.3+12
+
+* Don't quote the boundary header for `MultipartRequest`. This is more
+  compatible with server quirks.
+
+## 0.11.3+11
+
+* Fix the SDK constraint to only include SDK versions that support importing
+  `dart:io` everywhere.
+
+## 0.11.3+10
+
+* Stop using `dart:mirrors`.
+
+## 0.11.3+9
+
+* Remove an extra newline in multipart chunks.
+
+## 0.11.3+8
+
+* Properly specify `Content-Transfer-Encoding` for multipart chunks.
+
+## 0.11.3+7
+
+* Declare compatibility with `http_parser` 3.0.0.
+
+## 0.11.3+6
+
+* Fix one more strong mode warning in `http/testing.dart`.
+
+## 0.11.3+5
+
+* Fix some lingering strong mode warnings.
+
+## 0.11.3+4
+
+* Fix all strong mode warnings.
+
+## 0.11.3+3
+
+* Support `http_parser` 2.0.0.
+
+## 0.11.3+2
+
+* Require Dart SDK >= 1.9.0
+
+* Eliminate many uses of `Chain.track` from the `stack_trace` package.
+
+## 0.11.3+1
+
+* Support `http_parser` 1.0.0.
+
+## 0.11.3
+
+* Add a `Client.patch` shortcut method and a matching top-level `patch` method.
+
+## 0.11.2
+
+* Add a `BrowserClient.withCredentials` property.
+
+## 0.11.1+3
+
+* Properly namespace an internal library name.
+
+## 0.11.1+2
+
+* Widen the version constraint on `unittest`.
+
+## 0.11.1+1
+
+* Widen the version constraint for `stack_trace`.
+
+## 0.11.1
+
+* Expose the `IOClient` class which wraps a `dart:io` `HttpClient`.
+
+## 0.11.0+1
+
+* Fix a bug in handling errors in decoding XMLHttpRequest responses for
+  `BrowserClient`.
+
+## 0.11.0
+
+* The package no longer depends on `dart:io`. The `BrowserClient` class in
+  `package:http/browser_client.dart` can now be used to make requests on the
+  browser.
+
+* Change `MultipartFile.contentType` from `dart:io`'s `ContentType` type to
+  `http_parser`'s `MediaType` type.
+
+* Exceptions are now of type `ClientException` rather than `dart:io`'s
+  `HttpException`.
+
+## 0.10.0
+
+* Make `BaseRequest.contentLength` and `BaseResponse.contentLength` use `null`
+  to indicate an unknown content length rather than -1.
+
+* The `contentLength` parameter to `new BaseResponse` is now named rather than
+  positional.
+
+* Make request headers case-insensitive.
+
+* Make `MultipartRequest` more closely adhere to browsers' encoding conventions.

+A composable, Future-based library for making HTTP requests.
+
+This package contains a set of high-level functions and classes that make it
+easy to consume HTTP resources. It's multi-platform (mobile, desktop, and
+browser) and supports multiple implementations.
+
+## Using
+
+The easiest way to use this library is via the top-level functions. They allow
+you to make individual HTTP requests with minimal hassle:
+
+```dart
+import 'package:http/http.dart' as http;
+
+var url = Uri.https('example.com', 'whatsit/create');
+var response = await http.post(url, body: {'name': 'doodle', 'color': 'blue'});
+print('Response status: ${response.statusCode}');
+print('Response body: ${response.body}');
+
+print(await http.read(Uri.https('example.com', 'foobar.txt')));
+```
+
+> [!NOTE]
+> Flutter applications may require
+> [additional configuration](https://docs.flutter.dev/data-and-backend/networking#platform-notes)
+> to make HTTP requests.
+
+If you're making multiple requests to the same server, you can keep open a
+persistent connection by using a [Client][] rather than making one-off requests.
+If you do this, make sure to close the client when you're done:
+
+```dart
+var client = http.Client();
+try {
+  var response = await client.post(
+      Uri.https('example.com', 'whatsit/create'),
+      body: {'name': 'doodle', 'color': 'blue'});
+  var decodedResponse = jsonDecode(utf8.decode(response.bodyBytes)) as Map;
+  var uri = Uri.parse(decodedResponse['uri'] as String);
+  print(await client.get(uri));
+} finally {
+  client.close();
+}
+```
+
+> [!TIP]
+> For detailed background information and practical usage examples, see:
+> - [Dart Development: Fetch data from the internet](https://dart.dev/tutorials/server/fetch-data)
+> - [Flutter Cookbook: Fetch data from the internet](https://docs.flutter.dev/cookbook/networking/fetch-data)
+> - [The Flutter HTTP example application][flutterhttpexample]
+
+You can also exert more fine-grained control over your requests and responses by
+creating [Request][] or [StreamedRequest][] objects yourself and passing them to
+[Client.send][].
+
+[Request]: https://pub.dev/documentation/http/latest/http/Request-class.html
+[StreamedRequest]: https://pub.dev/documentation/http/latest/http/StreamedRequest-class.html
+[Client.send]: https://pub.dev/documentation/http/latest/http/Client/send.html
+
+This package is designed to be composable. This makes it easy for external
+libraries to work with one another to add behavior to it. Libraries wishing to
+add behavior should create a subclass of [BaseClient][] that wraps another
+[Client][] and adds the desired behavior:
+
+[BaseClient]: https://pub.dev/documentation/http/latest/http/BaseClient-class.html
+[Client]: https://pub.dev/documentation/http/latest/http/Client-class.html
+
+```dart
+class UserAgentClient extends http.BaseClient {
+  final String userAgent;
+  final http.Client _inner;
+
+  UserAgentClient(this.userAgent, this._inner);
+
+  Future<http.StreamedResponse> send(http.BaseRequest request) {
+    request.headers['user-agent'] = userAgent;
+    return _inner.send(request);
+  }
+}
+```
+
+## Retrying requests
+
+`package:http/retry.dart` provides a class [`RetryClient`][RetryClient] to wrap
+an underlying [`http.Client`][Client] which transparently retries failing
+requests.
+
+[RetryClient]: https://pub.dev/documentation/http/latest/retry/RetryClient-class.html
+[Client]: https://pub.dev/documentation/http/latest/http/Client-class.html
+
+```dart
+import 'package:http/http.dart' as http;
+import 'package:http/retry.dart';
+
+Future<void> main() async {
+  final client = RetryClient(http.Client());
+  try {
+    print(await client.read(Uri.http('example.org', '')));
+  } finally {
+    client.close();
+  }
+}
+```
+
+By default, this retries any request whose response has status code 503
+Temporary Failure up to three retries. It waits 500ms before the first retry,
+and increases the delay by 1.5x each time. All of this can be customized using
+the [`RetryClient()`][new RetryClient] constructor.
+
+[new RetryClient]: https://pub.dev/documentation/http/latest/retry/RetryClient/RetryClient.html
+
+## Choosing an implementation
+
+There are multiple implementations of the `package:http` [`Client`][client] interface. By default, `package:http` uses [`BrowserClient`][browserclient] on the web and [`IOClient`][ioclient] on all other platforms. You can choose a different [`Client`][client] implementation based on the needs of your application.
+
+You can change implementations without changing your application code, except
+for a few lines of [configuration](#2-configure-the-http-client).
+
+Some well-supported implementations are:
+
+| Implementation | Supported Platforms | SDK | Caching | HTTP3/QUIC | Platform Native | 
+| -------------- | ------------------- | ----| ------- | ---------- | --------------- |
+| `package:http` — [`IOClient`][ioclient] | Android, iOS, Linux, macOS, Windows | Dart, Flutter | ❌ | ❌ | ❌ |
+| `package:http` — [`BrowserClient`][browserclient] | Web | Dart, Flutter | ― | ✅︎ | ✅︎ | Dart, Flutter |
+| [`package:cupertino_http`][cupertinohttp] — [`CupertinoClient`][cupertinoclient] | iOS, macOS | Flutter | ✅︎ | ✅︎ | ✅︎ |
+| [`package:cronet_http`][cronethttp] — [`CronetClient`][cronetclient] | Android | Flutter | ✅︎ | ✅︎ | ― |
+| [`package:fetch_client`][fetch] — [`FetchClient`][fetchclient] | Web | Dart, Flutter | ✅︎ | ✅︎ | ✅︎ |
+
+> [!TIP]
+> If you are writing a Dart package or Flutter plugin that uses
+> `package:http`, you should not depend on a particular [`Client`][client]
+> implementation. Let the application author decide what implementation is
+> best for their project. You can make that easier by accepting an explicit
+> [`Client`][client] argument. For example:
+>
+> ```dart
+> Future<Album> fetchAlbum({Client? client}) async {
+>   client ??= Client();
+>   ...
+> }
+> ```
+
+## Configuration
+
+To use an HTTP client implementation other than the default, you must:
+1. Add the HTTP client as a dependency.
+2. Configure the HTTP client.
+3. Connect the HTTP client to the code that uses it.
+
+### 1. Add the HTTP client as a dependency.
+
+To add a package compatible with the Dart SDK to your project, use `dart pub add`.
+
+For example:
+
+```terminal
+# Replace  "fetch_client" with the package that you want to use.
+dart pub add fetch_client
+```
+
+To add a package that requires the Flutter SDK, use `flutter pub add`.
+
+For example:
+
+```terminal
+# Replace  "cupertino_http" with the package that you want to use.
+flutter pub add cupertino_http
+```
+
+### 2. Configure the HTTP client.
+
+Different `package:http` [`Client`][client] implementations may require
+different configuration options.
+
+Add a function that returns a correctly configured [`Client`][client]. You can
+return a different [`Client`][client] on different platforms.
+
+For example:
+
+```dart
+Client httpClient() {
+  if (Platform.isAndroid) {
+    final engine = CronetEngine.build(
+        cacheMode: CacheMode.memory,
+        cacheMaxSize: 1000000);
+    return CronetClient.fromCronetEngine(engine);
+  }
+  if (Platform.isIOS || Platform.isMacOS) {
+    final config = URLSessionConfiguration.ephemeralSessionConfiguration()
+      ..cache = URLCache.withCapacity(memoryCapacity: 1000000);
+    return CupertinoClient.fromSessionConfiguration(config);
+  }
+  return IOClient();
+}
+```
+
+> [!TIP]
+> [The Flutter HTTP example application][flutterhttpexample] demonstrates
+> configuration best practices.
+
+#### Supporting browser and native
+
+If your application can be run in the browser and natively, you must put your
+browser and native configurations in separate files and import the correct file
+based on the platform.
+
+For example:
+
+```dart
+// -- http_client_factory.dart
+Client httpClient() {
+  if (Platform.isAndroid) {
+    return CronetClient.defaultCronetEngine();
+  }
+  if (Platform.isIOS || Platform.isMacOS) {
+    return CupertinoClient.defaultSessionConfiguration();
+  }
+  return IOClient();
+}
+```
+
+```dart
+// -- http_client_factory_web.dart
+Client httpClient() => FetchClient();
+```
+
+```dart
+// -- main.dart
+import 'http_client_factory.dart'
+    if (dart.library.js_interop) 'http_client_factory_web.dart'
+
+// The correct `httpClient` will be available.
+```
+
+### 3. Connect the HTTP client to the code that uses it.
+
+The best way to pass [`Client`][client] to the places that use it is
+explicitly through arguments.
+
+For example:
+
+```dart
+void main() {
+  final client = httpClient();
+  fetchAlbum(client, ...);
+}
+```
+
+When using the Flutter SDK, you can use a one of many
+[state management approaches][flutterstatemanagement].
+
+> [!TIP]
+> [The Flutter HTTP example application][flutterhttpexample] demonstrates
+> how to make the configured [`Client`][client] available using
+> [`package:provider`][provider] and
+> [`package:http_image_provider`][http_image_provider].
+
+When using the Dart SDK, you can use [`runWithClient`][runwithclient] to
+ensure that the correct [`Client`][client] is used when explicit argument
+passing is not an option. For example, if you depend on code that uses
+top-level functions (e.g. `http.post`) or calls the
+[`Client()`][clientconstructor] constructor. When an [Isolate][isolate] is
+spawned, it does not inherit any variables from the calling Zone, so
+`runWithClient` needs to be used in each Isolate that uses `package:http`.
+
+You can ensure that only the `Client` that you have explicitly configured is
+used by defining `no_default_http_client=true` in the environment. This will
+also allow the default `Client` implementation to be removed, resulting in
+a reduced application size.
+
+```terminal
+$ flutter build appbundle --dart-define=no_default_http_client=true ...
+$ dart compile exe --define=no_default_http_client=true ...
+```

+This library provides an http/2 interface on top of a bidirectional stream of bytes.
+
+## Usage
+
+Here is a minimal example of connecting to a http/2 capable server, requesting
+a resource and iterating over the response.
+
+```dart
+import 'dart:convert';
+import 'dart:io';
+
+import 'package:http2/http2.dart';
+
+Future<void> main() async {
+  final uri = Uri.parse('https://www.google.com/');
+
+  final transport = ClientTransportConnection.viaSocket(
+    await SecureSocket.connect(
+      uri.host,
+      uri.port,
+      supportedProtocols: ['h2'],
+    ),
+  );
+
+  final stream = transport.makeRequest(
+    [
+      Header.ascii(':method', 'GET'),
+      Header.ascii(':path', uri.path),
+      Header.ascii(':scheme', uri.scheme),
+      Header.ascii(':authority', uri.host),
+    ],
+    endStream: true,
+  );
+
+  await for (var message in stream.incomingMessages) {
+    if (message is HeadersStreamMessage) {
+      for (var header in message.headers) {
+        final name = utf8.decode(header.name);
+        final value = utf8.decode(header.value);
+        print('Header: $name: $value');
+      }
+    } else if (message is DataStreamMessage) {
+      // Use [message.bytes] (but respect 'content-encoding' header)
+    }
+  }
+  await transport.finish();
+}
+```
+
+An example with better error handling is available [here][example].
+
+See the [API docs][api] for more details.

+
+/// This library provides an http/2 interface on top of a bidirectional stream
+/// of bytes.
+///
+/// The client and server sides can be created via [ClientTransportStream] and
+/// [ServerTransportStream] respectively. Both sides can be configured via
+/// settings (see [ClientSettings] and [ServerSettings]). The settings will be
+/// communicated to the remote peer (if necessary) and will be valid during the
+/// entire lifetime of the connection.
+///
+/// A http/2 transport allows a client to open a bidirectional stream (see
+/// [ClientTransportConnection.makeRequest]) and a server can open (or push) a
+/// unidirectional stream to the client via [ServerTransportStream.push].
+///
+/// In both cases (unidirectional and bidirectional stream), one can send
+/// headers and data to the other side (via [HeadersStreamMessage] and
+/// [DataStreamMessage]). These messages are ordered and will arrive in the same
+/// order as they were sent (data messages may be split up into multiple smaller
+/// chunks or might be combined).
+///
+/// In the most common case, each direction will send one [HeadersStreamMessage]
+/// followed by zero or more [DataStreamMessage]s.
+///
+/// Establishing a bidirectional stream of bytes to a server is up to the user
+/// of this library. There are 3 common ways to achive this
+///
+///     * connect to a server via SSL and use the ALPN (SSL) protocol extension
+///       to negotiate with the server to speak http/2 (the ALPN protocol
+///       identifier for http/2 is `h2`)
+///
+///     * have prior knowledge about the server - i.e. know ahead of time that
+///       the server will speak http/2 via an unencrypted tcp connection
+///
+///     * use a http/1.1 connection and upgrade it to http/2
+///
+/// The first way is the most common way and can be done in Dart by using
+/// `dart:io`s secure socket implementation (by using a `SecurityContext` and
+/// including 'h2' in the list of protocols used for ALPN).
+///
+/// A simple example on how to connect to a http/2 capable server and
+/// requesting a resource is available at https://github.com/dart-lang/http2/blob/master/example/display_headers.dart.

+[![pub package](https://img.shields.io/pub/v/http_client_conformance_tests.svg)](https://pub.dev/packages/http_client_conformance_tests)
+
+A library that tests whether implementations of `package:http`
+[`Client`](https://pub.dev/documentation/http/latest/http/Client-class.html)
+behave as expected.
+
+This package is intended to be used in the tests of packages that implement
+`package:http`
+[`Client`](https://pub.dev/documentation/http/latest/http/Client-class.html).
+
+The tests work by starting a series of test servers and running the provided
+`package:http`
+[`Client`](https://pub.dev/documentation/http/latest/http/Client-class.html)
+against them.
+
+## Usage
+
+`package:http_client_conformance_tests` is meant to be used in the tests suite
+of a `package:http`
+[`Client`](https://pub.dev/documentation/http/latest/http/Client-class.html)
+like:
+
+```dart
+import 'package:http/http.dart';
+import 'package:test/test.dart';
+
+import 'package:http_client_conformance_tests/http_client_conformance_tests.dart';
+
+class MyHttpClient extends BaseClient {
+  @override
+  Future<StreamedResponse> send(BaseRequest request) async {
+    // Your implementation here.
+  }
+}
+
+void main() {
+  group('client conformance tests', () {
+    testAll(MyHttpClient());
+  });
+}
+```
+
+**Note**: This package does not have its own tests, instead it is
+exercised by the tests in `package:http`.

+## 4.1.1
+
+* Move to `dart-lang/http` monorepo.
+
+## 4.1.0
+
+* `CaseInsensitiveMap`: added constructor `fromEntries`.
+* Require `package:collection` `^1.19.0`
+* Require Dart `^3.4.0`
+
+## 4.0.2
+
+* Remove `package:charcode` from dev_dependencies.
+
+## 4.0.1
+
+* Remove dependency on `package:charcode`.
+
+## 4.0.0
+
+* Stable null safety stable release.
+
+## 4.0.0-nullsafety
+
+* Migrate to null safety.
+
+## 3.1.4
+
+* Fixed lints affecting package health score.
+* Added an example.
+
+## 3.1.3
+
+* Set max SDK version to `<3.0.0`, and adjust other dependencies.
+
+## 3.1.2
+
+* Require Dart SDK 2.0.0-dev.17.0 or greater.
+
+* A number of strong-mode fixes.
+
+## 3.1.1
+
+* Fix a logic bug in the `chunkedCoding` codec. It had been producing invalid
+  output and rejecting valid input.
+
+## 3.1.0
+
+* Add `chunkedCoding`, a `Codec` that supports encoding and decoding the
+  [chunked transfer coding][].
+
+[chunked transfer coding]: https://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1
+
+## 3.0.2
+
+* Support `string_scanner` 1.0.0.
+
+## 3.0.1
+
+* Remove unnecessary dependencies.
+
+## 3.0.0
+
+* All deprecated APIs have been removed. No new APIs have been added. Packages
+  that would use 3.0.0 as a lower bound should use 2.2.0 instead—for example,
+  `http_parser: ">=2.2.0 <4.0.0"`.
+
+* Fix all strong-mode warnings.
+
+## 2.2.1
+
+* Add support for `crypto` 1.0.0.
+
+## 2.2.0
+
+* `WebSocketChannel` has been moved to
+  [the `web_socket_channel` package][web_socket_channel]. The implementation
+  here is now deprecated.
+
+[web_socket_channel]: https://pub.dev/packages/web_socket_channel
+
+## 2.1.0
+
+* Added `WebSocketChannel`, an implementation of `StreamChannel` that's backed
+  by a `WebSocket`.
+
+* Deprecated `CompatibleWebSocket` in favor of `WebSocketChannel`.
+
+## 2.0.0
+
+* Removed the `DataUri` class. It's redundant with the `Uri.data` getter that's
+  coming in Dart 1.14, and the `DataUri.data` field in particular was an invalid
+  override of that field.
+
+## 1.1.0
+
+* The MIME spec says that media types and their parameter names are
+  case-insensitive. Accordingly, `MediaType` now uses a case-insensitive map for
+  its parameters and its `type` and `subtype` fields are now always lowercase.
+
+## 1.0.0
+
+This is 1.0.0 because the API is stable—there are no breaking changes.
+
+* Added an `AuthenticationChallenge` class for parsing and representing the
+  value of `WWW-Authenticate` and related headers.
+
+* Added a `CaseInsensitiveMap` class for representing case-insensitive HTTP
+  values.
+
+## 0.0.2+8
+
+* Bring in the latest `dart:io` WebSocket code.
+
+## 0.0.2+7
+
+* Add more detail to the readme.
+
+## 0.0.2+6
+
+* Updated homepage URL.
+
+## 0.0.2+5
+
+* Widen the version constraint on the `collection` package.
+
+## 0.0.2+4
+
+* Widen the `string_scanner` version constraint.
+
+## 0.0.2+3
+
+* Fix a library name conflict.
+
+## 0.0.2+2
+
+* Fixes for HTTP date formatting.
+
+## 0.0.2+1
+
+* Minor code refactoring.
+
+## 0.0.2
+
+* Added `CompatibleWebSocket`, for platform- and API-independent support for the
+  WebSocket API.

+
+`http_parser` is a platform-independent package for parsing and serializing
+various HTTP-related formats. It's designed to be usable on both the browser and
+the server, and thus avoids referencing any types from `dart:io` or `dart:html`.
+
+## Features
+
+* Support for parsing and formatting dates according to [HTTP/1.1][2616], the
+  HTTP/1.1 standard.
+
+* A `MediaType` class that represents an HTTP media type, as used in `Accept`
+  and `Content-Type` headers. This class supports both parsing and formatting
+  media types according to [HTTP/1.1][2616].
+
+* A `WebSocketChannel` class that provides a `StreamChannel` interface for both
+  the client and server sides of the [WebSocket protocol][6455] independently of
+  any specific server implementation.

+
+A package that allows HTTP clients outside of the Dart SDK to integrate with
+the DevTools Network View.
+
+**NOTE:** This package is meant for developers *implementing* HTTP clients, not
+developers *using* HTTP clients.
+
+## Using
+
+`HttpClientRequestProfile.profile` returns an `HttpClientRequestProfile` object
+if HTTP profiling is enabled. Populating the fields of that object with
+information about an HTTP request and about the response to that request will
+make that information show up in the
+[DevTools Network View](https://docs.flutter.dev/tools/devtools/network).
+
+```dart
+import 'package:http_profile/http_profile.dart';
+
+Future<String> get(Uri uri) {
+  final profile = HttpClientRequestProfile.profile(
+    requestStartTime: DateTime.now(),
+    requestMethod: 'GET',
+    requestUri: uri.toString(),
+  );
+  profile?.connectionInfo = {
+      'localPort': 1285,
+      'remotePort': 443,
+      'connectionPoolId': '21x23',
+    };
+
+  profile.requestData.proxyDetails = HttpProfileProxyData(
+    host: 'https://www.example.com',
+    username: 'abc123',
+    isDirect: true,
+    port: 4321,
+  );
+
+  // Make the HTTP request and populate the response data.
+
+  profile.responseData.headersListValues = {
+    'connection': ['keep-alive'],
+    'cache-control': ['max-age=43200'],
+    'content-type': ['application/json', 'charset=utf-8'],
+  };
+
+  return responseString;
+}
+```
+
+Refer to the source of
+[`package:cupertino_http`](https://github.com/dart-lang/http/blob/master/pkgs/cupertino_http/lib/src/cupertino_client.dart)
+to see a comprehensive example of how `package:http_profile` can be integrated
+into an HTTP client.
+
+## Status: pre-1.0
+
+**NOTE**: We are in the process of collecting feedback and iterating on this
+package, so new versions that include API and breaking changes may be published
+frequently.
+
+Your feedback is valuable and will help us evolve this package. For general
+feedback, suggestions, and comments, please file an issue in the
+[bug tracker](https://github.com/dart-lang/http/issues).

+## 0.1.1-wip
+
+- `OkHttpClient` now receives an `OkHttpClientConfiguration` to configure the client on a per-call basis.
+- `OkHttpClient` supports setting four types of timeouts: [`connectTimeout`](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-ok-http-client/-builder/connect-timeout.html), [`readTimeout`](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-ok-http-client/-builder/read-timeout.html), [`writeTimeout`](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-ok-http-client/-builder/write-timeout.html), and [`callTimeout`](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-ok-http-client/-builder/call-timeout.html), using the `OkHttpClientConfiguration`.
+- Update to `jnigen` 0.12.2
+
+## 0.1.0
+
+- Implementation of [`BaseClient`](https://pub.dev/documentation/http/latest/http/BaseClient-class.html) and `send()` method using [`enqueue()` API](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-call/enqueue.html)
+- `ok_http` can now send asynchronous requests and stream response bodies.
+- Add [DevTools Network View](https://docs.flutter.dev/tools/devtools/network) support.
+- WebSockets support is now available in the `ok_http` package. Wraps around the OkHttp [WebSocket API](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-web-socket/index.html).

+[![pub package](https://img.shields.io/pub/v/ok_http.svg)](https://pub.dev/packages/ok_http)
+[![package publisher](https://img.shields.io/pub/publisher/ok_http.svg)](https://pub.dev/packages/ok_http/publisher)
+
+An Android Flutter plugin that provides access to the
+[OkHttp][] HTTP client and the OkHttp [WebSocket][] API.
+
+## Why use `package:ok_http`?
+
+### 👍 Increased compatibility and reduced disk profile
+
+`package:ok_http` is smaller and works on more devices than other packages.
+
+This size of the [example application][] APK file using different packages:
+
+| Package | APK Size (MiB) |
+|-|-|
+| **`ok_http`** | **20.3**  |
+| [`cronet_http`](https://pub.dev/packages/cronet_http) [^1] | 20.6 |
+| [`cronet_http` (embedded)](https://pub.dev/packages/cronet_http#use-embedded-cronet) [^2] | 34.4 |
+| `dart:io` [^3] | 20.4 |
+
+[^1]: Requires [Google Play Services][], which are not available on all devices.
+[^2]: Embeds the Cronet HTTP library.
+[^3]: Accessed through [`IOClient`](https://pub.dev/documentation/http/latest/io_client/IOClient-class.html).
+
+### 🔌 Supports WebSockets out of the box
+
+`package:ok_http` wraps the OkHttp [WebSocket][] API which supports:
+
+- Configured System Proxy on Android
+- HTTP/2
+
+**Example Usage of `OkHttpWebSocket`:**
+
+```dart
+import 'package:ok_http/ok_http.dart';
+import 'package:web_socket/web_socket.dart';
+void main() async {
+  final socket = await OkHttpWebSocket.connect(
+      Uri.parse('wss://ws.postman-echo.com/raw'));
+  socket.events.listen((e) async {
+    switch (e) {
+      case TextDataReceived(text: final text):
+        print('Received Text: $text');
+        await socket.close();
+      case BinaryDataReceived(data: final data):
+        print('Received Binary: $data');
+      case CloseReceived(code: final code, reason: final reason):
+        print('Connection to server closed: $code [$reason]');
+    }
+  });
+}
+```
+
+## Status: experimental
+
+**NOTE**: This package is currently experimental and published under the
+[labs.dart.dev](https://dart.dev/dart-team-packages) pub publisher in order to
+solicit feedback.
+
+For packages in the labs.dart.dev publisher we generally plan to either graduate
+the package into a supported publisher (dart.dev, tools.dart.dev) after a period
+of feedback and iteration, or discontinue the package. These packages have a
+much higher expected rate of API and breaking changes.
+
+Your feedback is valuable and will help us evolve this package. For general
+feedback, suggestions, and comments, please file an issue in the
+[bug tracker](https://github.com/dart-lang/http/issues).

+
+## 0.1.2
+
+- Fix a `StateError` in `IOWebSocket` when data is received from the peer
+  after the connection has been closed locally.
+
+## 0.1.1
+
+- Add the ability to create a `package:web_socket` `WebSocket` given a
+  `dart:io` `WebSocket`.
+
+## 0.1.0
+
+- Basic functionality in place.

+[![package publisher](https://img.shields.io/pub/publisher/web_socket.svg)](https://pub.dev/packages/web_socket/publisher)
+
+Any easy-to-use library for communicating with
+[WebSockets](https://en.wikipedia.org/wiki/WebSocket) that has multiple
+implementations.
+
+## Why another WebSocket package?
+
+The goal of `package:web_socket` is to provide a simple, well-defined 
+[WebSockets](https://en.wikipedia.org/wiki/WebSocket) interface that has
+consistent behavior across implementations.
+
+[`package:web_socket_channel`](https://pub.dev/documentation/web_socket_channel/)
+is currently the most popular WebSocket package. It has
+two implementations, one based on `package:web` and the other based on
+`dart:io` `WebSocket`. But those implementations do not have consistent
+behavior.
+
+[`WebSocket`](https://pub.dev/documentation/web_socket/latest/web_socket/WebSocket-class.html)
+currently has three implementations (with more on the way) that
+all pass the same set of
+[conformance tests](https://github.com/dart-lang/http/tree/master/pkgs/web_socket_conformance_tests):
+
+* [`BrowserWebSocket`](https://pub.dev/documentation/web_socket/latest/browser_web_socket/BrowserWebSocket-class.html)
+* [`CupertinoWebSocket`](https://pub.dev/documentation/cupertino_http/latest/cupertino_http/CupertinoWebSocket-class.html)
+* [`IOWebSocket`](https://pub.dev/documentation/web_socket/latest/io_web_socket/IOWebSocket-class.html)
+
+## Using
+
+```dart
+import 'package:web_socket/web_socket.dart';
+
+void main() async {
+  final socket =
+      await WebSocket.connect(Uri.parse('wss://ws.postman-echo.com/raw'));
+
+  socket.events.listen((e) async {
+    switch (e) {
+      case TextDataReceived(text: final text):
+        print('Received Text: $text');
+        await socket.close();
+      case BinaryDataReceived(data: final data):
+        print('Received Binary: $data');
+      case CloseReceived(code: final code, reason: final reason):
+        print('Connection to server closed: $code [$reason]');
+    }
+  });
+
+  socket.sendText('Hello Dart WebSockets! 🎉');
+}
+```
+
+## Status: experimental
+
+**NOTE**: This package is currently experimental and published under the
+[labs.dart.dev](https://dart.dev/dart-team-packages) pub publisher in order to
+solicit feedback.
+
+For packages in the labs.dart.dev publisher we generally plan to either graduate
+the package into a supported publisher (dart.dev, tools.dart.dev) after a period
+of feedback and iteration, or discontinue the package. These packages have a
+much higher expected rate of API and breaking changes.
+
+Your feedback is valuable and will help us evolve this package. For general
+feedback, suggestions, and comments, please file an issue in the
+[bug tracker](https://github.com/dart-lang/http/issues).

+[![pub package](https://img.shields.io/pub/v/web_socket_conformance_tests.svg)](https://pub.dev/packages/web_socket_conformance_tests)
+
+A library that tests whether implementations of `package:web_socket`
+`WebSocket` behave as expected.
+
+This package is intended to be used in the tests of packages that implement
+`package:web_socket` `Socket`.
+
+The tests work by starting a series of test servers and running the provided
+`package:web_socket` `WebSocket` against them.
+
+## Usage
+
+`package:web_socket_conformance_tests` is meant to be used in the tests suite
+of a `package:web_socket` `WebSocket` like:
+
+```dart
+import 'package:web_socket/web_socket.dart';
+import 'package:test/test.dart';
+
+import 'package:web_socket_conformance_tests/web_socket_conformance_tests.dart';
+
+class MyWebSocket implements WebSocket {
+  // Your implementation here.
+}
+
+void main() {
+  group('WebSocket conformance tests', () {
+    testAll(MyWebSocket());
+  });
+}
+```
+
+**Note**: This package does not have its own tests, instead it is
+exercised by the tests in `package:web_socket`.
