+
+## 5.0.1
+
+* Log a more detailed warning at build time about the previous AndroidX
+  migration.
+
+## 5.0.0
+
+* **Breaking change**. Migrate from the deprecated original Android Support
+  Library to AndroidX. This shouldn't result in any functional changes, but it
+  requires any Android apps using this plugin to [also
+  migrate](https://developer.android.com/jetpack/androidx/migrate) if they're
+  using the original support library.
+
+  This was originally incorrectly pushed in the `4.2.0` update.
+
+## 4.2.0+3
+
+* **Revert the breaking 4.2.0 update**. 4.2.0 was known to be breaking and
+  should have incremented the major version number instead of the minor. This
+  revert is in and of itself breaking for anyone that has already migrated
+  however. Anyone who has already migrated their app to AndroidX should
+  immediately update to `5.0.0` instead. That's the correctly versioned new push
+  of `4.2.0`.
+
+## 4.2.0+2
+
+* Updated `launch` to use async and await, fixed the incorrect return value by `launch` method.
+
+## 4.2.0+1
+
+* Refactored the Java and Objective-C code. Replaced instance variables with properties in Objective-C.
+
+## 4.2.0
+
+* **BAD**. This was a breaking change that was incorrectly published on a minor
+  version upgrade, should never have happened. Reverted by 4.2.0+3.
+
+* **Breaking change**. Migrate from the deprecated original Android Support
+  Library to AndroidX. This shouldn't result in any functional changes, but it
+  requires any Android apps using this plugin to [also
+  migrate](https://developer.android.com/jetpack/androidx/migrate) if they're
+  using the original support library.
+
+## 4.1.0+1
+
+* This is just a version bump to republish as 4.1.0 was published with some dirty local state.
+
+## 4.1.0
+
+* Added `universalLinksOnly` setting.
+* Updated `launch` to return `Future<bool>`.
+
+## 4.0.3
+
+* Fixed launch url fail for Android: `launch` now assert activity not null and using activity to startActivity.
+* Fixed `WebViewActivity has leaked IntentReceiver` for Android.
+
+## 4.0.2
+
+* Added `closeWebView` function to programmatically close the current WebView.
+
+## 4.0.1
+
+* Added enableJavaScript field to `launch` to enable javascript in Android WebView.
+
+## 4.0.0
+
+* **Breaking change** Now requires a minimum Flutter version of 0.5.6.
+* Update to statusBarBrightness field so that the logic runs on the Flutter side.
+* **Breaking change** statusBarBrightness no longer has a default value.
+
+## 3.0.3
+
+* Added statusBarBrightness field to `launch` to set iOS status bar brightness.
+
+## 3.0.2
+
+* Updated Gradle tooling to match Android Studio 3.1.2.
+
+## 3.0.1
+
+* Fix a crash during Safari view controller dismiss.
+
+## 3.0.0
+
+* **Breaking change**. Set SDK constraints to match the Flutter beta release.
+
+## 2.0.2
+
+* Fixed Dart 2 issue: `launch` now returns `Future<void>` instead of
+  `Future<Null>`.
+
+## 2.0.1
+
+* Simplified and upgraded Android project template to Android SDK 27.
+* Updated package description.
+
+## 2.0.0
+
+* **Breaking change**. Upgraded to Gradle 4.1 and Android Studio Gradle plugin
+  3.0.1. Older Flutter projects need to upgrade their Gradle setup as well in
+  order to use this version of the plugin. Instructions can be found
+  [here](https://github.com/flutter/flutter/wiki/Updating-Flutter-projects-to-Gradle-4.1-and-Android-Studio-Gradle-plugin-3.0.1).
+
+## 1.0.3

+# url_launcher
+
+[![pub package](https://img.shields.io/pub/v/url_launcher.svg)](https://pub.dartlang.org/packages/url_launcher)
+
+A Flutter plugin for launching a URL in the mobile platform. Supports
+iOS, Android, web, Windows, macOS, and Linux.
+
+## Usage
+To use this plugin, add `url_launcher` as a [dependency in your pubspec.yaml file](https://flutter.dev/platform-plugins/).
+
+### Example
+
+``` dart
+import 'package:flutter/material.dart';
+import 'package:url_launcher/url_launcher.dart';
+
+void main() {
+  runApp(Scaffold(
+    body: Center(
+      child: RaisedButton(
+        onPressed: _launchURL,
+        child: Text('Show Flutter homepage'),
+      ),
+    ),
+  ));
+}
+
+_launchURL() async {
+  const url = 'https://flutter.dev';
+  if (await canLaunch(url)) {
+    await launch(url);
+  } else {
+    throw 'Could not launch $url';
+  }
+}
+
+```
+
+## Supported URL schemes
+
+The [`launch`](https://www.dartdocs.org/documentation/url_launcher/latest/url_launcher/launch.html) method
+takes a string argument containing a URL. This URL
+can be formatted using a number of different URL schemes. The supported
+URL schemes depend on the underlying platform and installed apps.
+
+Common schemes supported by both iOS and Android:
+
+| Scheme | Action |
+|---|---|
+| `http:<URL>` , `https:<URL>`, e.g. `http://flutter.dev` | Open URL in the default browser |
+| `mailto:<email address>?subject=<subject>&body=<body>`, e.g. `mailto:smith@example.org?subject=News&body=New%20plugin` | Create email to <email address> in the default email app |
+| `tel:<phone number>`, e.g. `tel:+1 555 010 999` | Make a phone call to <phone number> using the default phone app |
+| `sms:<phone number>`, e.g. `sms:5550101234` | Send an SMS message to <phone number> using the default messaging app |
+
+More details can be found here for [iOS](https://developer.apple.com/library/content/featuredarticles/iPhoneURLScheme_Reference/Introduction/Introduction.html) and [Android](https://developer.android.com/guide/components/intents-common.html)
+
+### Encoding URLs
+
+URLs must be properly encoded, especially when including spaces or other special characters. This can be done using the [`Uri` class](https://api.dart.dev/stable/2.7.1/dart-core/Uri-class.html):
+```dart
+import 'dart:core';
+import 'package:url_launcher/url_launcher.dart';
+
+final Uri _emailLaunchUri = Uri(
+  scheme: 'mailto',
+  path: 'smith@example.com',
+  queryParameters: {
+    'subject': 'Example Subject & Symbols are allowed!'
+  }
+);
+
+// ...
+
+// mailto:smith@example.com?subject=Example+Subject+%26+Symbols+are+allowed%21
+launch(_emailLaunchUri.toString());
+```
+
+## Handling missing URL receivers
+
+A particular mobile device may not be able to receive all supported URL schemes.
+For example, a tablet may not have a cellular radio and thus no support for
+launching a URL using the `sms` scheme, or a device may not have an email app
+and thus no support for launching a URL using the `email` scheme.
+
+We recommend checking which URL schemes are supported using the
+[`canLaunch`](https://www.dartdocs.org/documentation/url_launcher/latest/url_launcher/canLaunch.html)
+method prior to calling `launch`. If the `canLaunch` method returns false, as a
+best practice we suggest adjusting the application UI so that the unsupported
+URL is never triggered; for example, if the `email` scheme is not supported, a
+UI button that would have sent email can be changed to redirect the user to a
+web page using a URL following the `http` scheme.
+
+## Browser vs In-app Handling
+By default, Android opens up a browser when handling URLs. You can pass
+`forceWebView: true` parameter to tell the plugin to open a WebView instead.
+If you do this for a URL of a page containing JavaScript, make sure to pass in
+`enableJavaScript: true`, or else the launch method will not work properly. On
+iOS, the default behavior is to open all web URLs within the app. Everything
+else is redirected to the app handler.
