[vm/inliner] Tweak inlining heuristic, improve List.of inlining. Builds on top of https://dart-review.googlesource.com/c/sdk/+/228660, introduces vm:vm:always-consider-inlining that tell inliner not to give up inlining of a function. HashMap constructor got prefer-inline pragma to accommodate shift in inlining away from where it used to be inlined due to large size of inlined HashMap, greater than FLAG_inline_getters_setters_smaller_than heuristic. Notable performance changes: JIT (x64) === ListCopy.List.of.fixed.100 27.37% ListCopy.List.of.fixed.2 16.31% AOT (x64) === Empty -9.978% InstantiateTypeArgs.Instantiate1 -8.262% ...

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.
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.

If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents on our wiki.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
