[VM] Fixes bug in CodeDeserial..::PostLoad due to Code::function. This was triggered by 85360 which introduced external code observers called during dart init. The bug is however susceptible to racing as tests often shutdown the VM before the code is fully deserialised. Code::function() is deceptive as it does in fact not guarantee that its return value is a Function. This in turn caused observer code to try access non-exists members on not-actually-Functions. Tested: tools/test.py -n dartk-asan-linux-debug-x64 vm/cc/DartAPI_DartInitializeCallsCodeObserver Change-Id: I12e367be06a3630d2d401a37b9097273c13f31e1 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/107289 Commit-Queue: Clement Skau <cskau@google.com> Reviewed-by: 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 has 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.

If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.

The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
