Fix snapshot fingerprinting in --preview-dart-2 mode. (#14843) * Fix snapshot fingerprinting in --preview-dart-2 mode. This is a follow up to PR #14775 - instead of treating dill file as an input treat as intermediate file and don't fingerprint it. Make sure to always use original main Dart file as an entry point for fingerprint calculation. This fixes an issue that AOT snapshot would not be recompiled in the preview-dart-2 mode if entry point changes, e.g. $ flutter build aot -t t/x.dart --preview-dart-2 $ flutter build aot -t t/y.dart --preview-dart-2 The second invocation would not build AOT snapshot.

A new mobile app SDK to help developers and designers build modern mobile apps for iOS and Android. Flutter is an alpha, open-source project.
Flutter's hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.
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.
