'Update Engine revision to caaafc5604ee9172293eb84a381be6aadd660317 for stable release 3.0.1' (#104213)
Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter tool may occasionally download resources from Google servers. By downloading or using the Flutter SDK you agree to the Google Terms of Service: https://policies.google.com/terms
For example, when installed from GitHub (as opposed to from a prepackaged archive), the Flutter tool will download the Dart SDK from Google servers immediately when first run, as it is used to execute the
flutter tool itself. This will also occur when Flutter is upgraded (e.g. by running the
flutter upgrade command).
We think Flutter will help you create beautiful, fast apps, with a productive, extensible and open development model, whether you're targeting iOS or Android, web, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of your choice.
We want to enable designers to deliver their full creative vision without being forced to water it down due to limitations of the underlying framework. Flutter‘s layered architecture gives you control over every pixel on the screen and its powerful compositing capabilities let you overlay and animate graphics, video, text, and controls without limitation. Flutter includes a full set of widgets that deliver pixel-perfect experiences whether you’re building for iOS (Cupertino) or Android (Material), along with support for customizing or creating entirely new visual components.
Flutter offers stateful hot reload, allowing you to make changes to your code and see the results instantly without restarting your app or losing its state.
Flutter works with any development tool (or none at all), and also includes editor plug-ins for both Visual Studio Code and IntelliJ / Android Studio. Flutter provides tens of thousands of packages to speed your development, regardless of your target platform. And accessing other native code is easy, with support for both FFI and platform-specific APIs.
Flutter is a fully open-source project, and we welcome contributions. Information on how to get started can be found in our contributor guide.
