This change includes the following: * Decision to use subtype range checks is revised to work regardless of the NNBD mode. * Handling of dynamic/Object/void is removed from SlowTypeTest stub as we use TopTypeTypeTest stub for the top types. That handling was unnecessary but harmless. However, in NNBD strong mode it becomes incorrect for non-nullable Object. * TypeTestingStubGenerator::OptimizedCodeForType now falls back to TypeTestingStubGenerator::DefaultCodeForType instead of directly using StubCode::DefaultTypeTest(). This refactoring is needed to avoid duplicating a more complicated logic in TypeTestingStubGenerator::DefaultCodeForType in the future.

Dart
A client-optimized language for fast apps on any platform
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).
License & patents
Dart is free and open source.
