**Note**: The Flutter team is currently trialing the use of [Gemini Code
Assist for
GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code).
Comments from the `gemini-code-assist` bot should not be taken as
authoritative feedback from the Flutter team. If you find its comments
useful you can update your code accordingly, but if you are unsure or
disagree with the feedback, please feel free to wait for a Flutter team
member's review for guidance on which automated comments should be
addressed.

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.
## Documentation
* [Install Flutter](https://flutter.dev/get-started/)
* [Flutter documentation](https://docs.flutter.dev/)
* [Development wiki](./docs/README.md)
* [Contributing to Flutter](https://github.com/flutter/flutter/blob/main/CONTRIBUTING.md)
For announcements about new releases, follow the
[flutter-announce@googlegroups.com](https://groups.google.com/forum/#!forum/flutter-announce)
mailing list. Our documentation also tracks [breaking
changes](https://docs.flutter.dev/release/breaking-changes) across releases.
## Terms of service
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).
## About Flutter
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.
### Beautiful user experiences
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][widget catalog] that deliver pixel-perfect experiences whether
you're building for iOS ([Cupertino]) or other platforms ([Material]), along with
support for customizing or creating entirely new visual components.

### Fast results
Flutter is fast. It's powered by hardware-accelerated 2D graphics
libraries like [Skia] (which underpins Chrome and Android) and
[Impeller]. We architected Flutter to
support glitch-free, jank-free graphics at the native speed of your device.
Flutter code is powered by the world-class [Dart platform], which enables
compilation to 32-bit and 64-bit ARM machine code for iOS and Android,
JavaScript and WebAssembly for the web, as well as Intel x64 and ARM
for desktop devices.

### Productive development
Flutter offers [stateful hot reload][Hot reload], allowing you to make changes to your code
and see the results instantly without restarting your app or losing its state.

### Extensible and open model
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][Flutter packages] to speed your
development, regardless of your target platform. And accessing other native code
is easy, with support for both FFI ([on Android][Android FFI], [on iOS][iOS FFI],
[on macOS][macOS FFI], and [on Windows][Windows FFI]) as well as
[platform-specific APIs][platform channels].
Flutter is a fully open-source project, and we welcome contributions.
