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

For announcements about new releases, follow the flutter-announce@googlegroups.com mailing list. Our documentation also tracks 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 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 the same hardware-accelerated 2D graphics library that underpins Chrome and Android: Skia. 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, as well as JavaScript for the web and Intel x64 for desktop devices.

Productive development

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.

Hot reload animation

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 to speed your development, regardless of your target platform. And accessing other native code is easy, with support for both FFI (on Android, on iOS, on macOS, and on Windows) as well as 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.

Fast results
Flutter is fast. It's powered by the same hardware-accelerated 2D graphics
library that underpins Chrome and Android: Skia. 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, as well
as JavaScript for the web and Intel x64 for desktop devices.

Productive development
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.
Hot reload animation
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 to speed your
development, regardless of your target platform. And accessing other native code
is easy, with support for both FFI (on Android, on iOS,
on macOS, and on Windows) as well as
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.

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
For announcements about new releases, follow the
flutter-announce@googlegroups.com
mailing list. Our documentation also tracks 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 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.
