web/CHANGELOG.md

2.0.0-wip

Added missing FileReader event getters: onAbort, onError, onLoad, onLoadStart, onProgress.
Removed renames UnderlyingSource and UnderlyingSourceBase where the types don't exist.
Fixed generation of variadic arguments to generate 4 optional parameters.
Removed all @Deprecated members.
Added URL.toDart and Uri.toJS extension methods.

Added HttpStatus class that declares http status codes. This is a copy of the HttpStatus from the dart:_internal library that's exposed only through dart:io and dart:html.
Added JSImmutableListWrapper which helps create a dart list from a JS list.
Deprecated TouchListWrapper and TouchListConvert in favor of JSImmutableListWrapper.
Added [] and []= overloaded operators to types which define unnamed getters and setters, respectively.
Exposed constants with primitive values as non-external so they can be switched over.
Add an extension responseHeaders to XMLHttpRequest.
Correctly namespace WebAssembly types.
Added CrossOriginWindow and CrossOriginLocation wrappers for cross-origin windows and locations, respectively, that can be accessed through HTMLIFrameElement.contentWindowCrossOrigin, Window.openCrossOrigin, Window.openerCrossOrigin, Window.topCrossOrigin, and Window.parentCrossOrigin.

Added supertypes' fields to dictionary constructors as dictionaries are allowed to contain those fields.
Empty dictionary constructors now create an empty object instead of being treated like non-object literal external constructors.
Generate MDN API documentation for getters.
Update the docs for generated interface types to reference the MDN Web Docs project.
Address several broken links in API documentation.
Generate APIs based on if they‘re on track to be a standard and not experimental. This is a looser restriction from the previous requirement that APIs need to be implemented by Chrome, Firefox, and Safari. As part of this, dictionaries and typedefs are only emitted if they’re used by a generated API.
Added onUnload event stream to ElementEventGetters extension methods.
Expose ElementStream as a public class.
Require Dart ^3.4.0.
APIs that return a double value now return double instead of num. This is to avoid users accidentally downcasting num, which has different semantics depending on whether you compile to JS or Wasm. See issue #57 for more details.
Fix an issue where some union types didn't account for typedef nullability.

Add TrustedTypes members.
Include MDN API documentation as class and member dartdoc comments. Docs sourced from the MDN Web Docs project; attributions and copyright licensing by Mozilla Contributors is licensed under CC-BY-SA 2.5.
Add a constructor for each Element tag onto their respective Element interfaces.
Remove external Element constructors that would result in a runtime error.
Deprecate createAudioElement in favor of the HTMLAudioElement constructor.

Redeprecate APIs that were deprecated in 0.4.1 but undeprecated in 0.4.2.
Add support for dart fix migrations from dart:html classes to package:web classes.
Contribute a markdown file for the renamed classes from dart:html to package:web (see renames.md).
Migrate classes to use interop extension types that implement JSObject.
Add generics to APIs that use JSArray and JSPromise. Typedefs of a Dart primitive type are instead replaced with their JS type equivalent if they appear as a type parameter in order to conform with the type bounds of JSArray and JSPromise.
Changed record types to be JSObject instead of JSAny.
Reduce the number of DOM APIs we generate code for. Currently, the API needs to be standards-track, and be supported by Safari, Chrome, and Firefox.
Updated the source IDL version to 3.43.1.

Deprecate a few type aliases in favor of their standardized versions:

Deprecate the top-level createElementTag, createCanvasElement, createIFrameElement, and querySelector functions. Instead, use the standard creation and query methods on document.
Deprecate the client extension methods on MouseEvent and Touch. Instead, directly use the clientX and clientY properties.
Deprecate the HttpRequest API borrowed from dart:html. Consider migrating to package:http instead.

Undeprecate some APIs and helpers library that were deprecated in 0.4.1. Because deprecations are breaking in Flutter, they should be done in a breaking change.

Exported the helper libraries from web.dart.
Deprecated the helpers.dart library in favor of web.dart.
Updated the readme to include usage info and package status.
Added an example.
Added event extensions for WebSocket
Fixes to the return types of the append() and clone() extension methods on Node.
Deprecated NodeGlue.append in favor of Node.appendChild.
Deprecated NodeGlue.clone in favor of Node.cloneNode.
Updated @webref/css to 6.10.0.

Remove implements JSObject from all types. This is needed to move the JS types exposed in dart:js_interop to extension types. This subtyping will be added back in a future version when we move all package:web types to extension types.
Add onMessage getter to WindowEventGetters extension methods.
helpers.dart: expose the EventStreamProviders class.
Add createIFrameElement method to helpers.dart.
Updated types to account for union types.
Fixed issue where all JSAnys were treated as nullable.
Changed JSVoid to void.
interface mixins are no longer emitted as interfaces. Their members are instead added to the interface that mixes them in.

Updated source IDL to v3.39.1.
Fixed a bug where typedefs were not declared with the IDL type's nullability.
Types that were aliased to double are now aliased to num. This is to make it easier for users to pass integer values without going through a cast and to make migration from dart:html easier.

Updates SDK version minimum to 3.2.0-194.0.dev.
Removes isInstanceOfDomType as dart:js_interop now exposes instanceOfString.
