-**********************************************************
-**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.

-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.
