Adds TODO comments in appropriate places for future work that will move non-covariant type checks out of the closure body. Instead, the VM will perform them in the invoke field dispatcher (or NoSuchMethodFromCallStub if --no-lazy-dispatchers is used) when a dynamic call is detected. This change has minimal negative effects on the code size. Here are the code size change percentages for the Flutter Gallery in release mode: * ARM7 * Instructions: +0.0391% * ROData: -0.0040% * Total: +0.0239% * ARM8: * Instructions: No change * ROData: +0.0015% * Total: +0.0004% All other code size benchmarks are also <0.01% increase.

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.
