| 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. |

| ## About Flutter |
| |
| We think Flutter will help you create beautiful, fast apps, with a productive, |
| extensible and open development model. |
| |
| ### 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 on both |
| iOS and Android. |
| |

| |
| ### Fast results |
| |
| Flutter is fast. It's powered by the same hardware-accelerated [Skia] 2D |
| graphics library that underpins Chrome and Android. 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. |

| |
| ### Extensible and open model |
| |
| Flutter works with any development tool (or none at all), but includes editor |
| plug-ins for both [Visual Studio Code] and [IntelliJ / Android Studio]. Flutter |
| provides [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] and [platform-specific APIs][platform channels]. |
| |
| Flutter is a fully open source project, and we welcome contributions. |
| Information on how to get started can be found at our |
| [contributor guide](CONTRIBUTING.md). |
