Flutter is Google’s mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
Flutter's hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.
Quickly ship features with a focus on native end-user experiences. Layered architecture allows full customization, which results in incredibly fast rendering and expressive and flexible designs.
Delight your users with Flutter's built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.
Browse the widget catalog.
Easily compose your UI with Flutter's modern functional-reactive framework and rich set of platform, layout, and foundation widgets. Solve your tough UI challenges with powerful and flexible APIs for 2D, animation, gestures, effects, and more.
class CounterState extends State<Counter> { int counter = 0; void increment() { // Tells the Flutter framework that state has changed, // so the framework can run build() and update the display. setState(() { counter++; }); } Widget build(BuildContext context) { // This method is rerun every time setState is called. // The Flutter framework has been optimized to make rerunning // build methods fast, so that you can just rebuild anything that // needs updating rather than having to individually change // instances of widgets. return new Row( children: <Widget>[ new RaisedButton( onPressed: increment, child: new Text('Increment'), ), new Text('Count: $counter'), ], ); } }
Browse the widget catalog and learn more about the functional-reactive framework.
Make your app come to life with platform APIs, 3rd party SDKs, and native code. Flutter lets you reuse your existing Java/Kotlin and ObjC/Swift code, and access native features and SDKs on Android and iOS.
Accessing platform features is easy. Here is a snippet from our interop example:
Future<Null> getBatteryLevel() async { var batteryLevel = 'unknown'; try { int result = await methodChannel.invokeMethod('getBatteryLevel'); batteryLevel = 'Battery level: $result%'; } on PlatformException { batteryLevel = 'Failed to get battery level.'; } setState(() { _batteryLevel = batteryLevel; }); }
Learn how to use packages, or write platform channels, to access native code, APIs, and SDKs.
Flutter has the tools and libraries to help you easily bring your ideas to life on iOS and Android. If you don't have any mobile development experience, Flutter is an easy and fast way to build beautiful mobile apps. If you are an experienced iOS or Android developer, you can use Flutter for your views and leverage much of your existing Java/Kotlin/ObjC/Swift investment.
