Report unsafe BuildContext access in Future.then and more Fixes https://github.com/dart-lang/linter/issues/4923 In this change we now protect code inside callback arguments to functions like `Future.then`. For example: ```dart Future<int>.delayed(Duration(seconds: 1), (_) { return 42; }).then((int value) { Navigator.of(context).pop(); }); ``` In code like this, each reference to BuildContext must be guarded by a mounted check. There are a number of "protected functions" that the rule now checks: Constructors: * Future.new: 1st positional parameter * Future.delayed: 2nd positional parameter * Future.microtask: 1st positional parameter * Stream.eventTransformed: 2nd positional parameter * Stream.multi: 1st positional parameter * Stream.periodic: 2nd positional parameter * StreamController.new: 'onListen', 'onPause', 'onResume', and 'onCancel' named parameters * StreamController.broadcast: 'onListen' and 'onCancel' named parameters Instance Methods: * Future.catchError: first positional parameter, and 'test' named parameter * Future.onError: 1st positional parameter, and 'test' named parameter * Future.then: 1st positional parameter, and 'onError' named parameter * Future.timeout: 'onTimeout' named parameter * Future.whenComplete: 1st positional parameter * Stream.any: 1st positional parameter * Stream.asBroadcastStream: 'onListen' and 'onCancel' named parameters * Stream.asyncExpand: 1st positional parameter * Stream.asyncMap: 1st positional parameter * Stream.distinct: 1st positional parameter * Stream.expand: 1st positional parameter * Stream.firstWhere: first positional parameter, and 'orElse' named parameter * Stream.fold: second positional parameter * Stream.forEach: 1st positional parameter * Stream.handleError: 1st positional parameter, and 'test' named parameter * Stream.lastWhere: 1st positional parameter, and 'orElse' named parameter * Stream.listen: 1st positional parameter, and 'onError' and 'onDone' named parameters * Stream.map: 1st positional parameter * Stream.reduce: 1st positional parameter * Stream.singleWhere: 1st positional parameter, and 'orElse' named parameter * Stream.skipWhile: 1st positional parameter * Stream.takeWhile: 1st positional parameter * Stream.timeout: 'onTimeout' named parameter * Stream.where: 1st positional parameter * Stream.onData: 1st positional parameter * Stream.onDone: 1st positional parameter * Stream.onError: 1st positional parameter Static Methods: * Future.doWhile: 1st positional parameter * Future.forEach: 2nd positional parameter * Future.wait: 'cleanUp' named parameter Change-Id: I703d5cfbee5e8af1f703f40046832d66b9b59bc2 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/365541 Reviewed-by: Phil Quitslund <pquitslund@google.com> Commit-Queue: Samuel Rawlins <srawlins@google.com>
Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
