Reland "[vm] Fix some async* semantics issues: Only run generator if there's active subscription (not paused/cancelled)" This fixes an issue where VM would run the async* generator after a `yield` / `yield*` even though the subscription may be paused or cancelled. Furthermore this fixes an issue where `StackTrace.current` used in async* generator crashes VM and/or produces truncated stack trace. This fixes the following existing tests that were failing before: * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t08 * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t09 * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t10 * language/async_star/async_star_cancel_test * language/async_star/pause_test New in reland: Allow the generator to to cause cancelling it's own consumer. This addresses the issue of original revert -> see https://github.com/flutter/flutter/issues/101514 Issue https://github.com/flutter/flutter/issues/100441 Issue https://github.com/dart-lang/sdk/issues/48695 Issue https://github.com/dart-lang/sdk/issues/34775 TEST=vm/dart{,_2}/causal_stacks/flutter_regress_100441_test Change-Id: I091b7159d59ea15fc31162b4b6b17260d523d7cb Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/242400 Reviewed-by: Lasse Nielsen <lrn@google.com> Commit-Queue: Martin Kustermann <kustermann@google.com>
Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
