Flutter

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. For release and other announcements, join the flutter-announce mailing list. Our documentation also tracks breaking changes across releases. 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][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. 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 programming language], 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. 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. 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].
