Konstantin Shcheglov acac9ab11b Issue 37608. Use instantiated FunctionType for tear-off(s).
I was working of switching runtimeTypeMatch() to purely
typeSystem.isSubtypeOf(), without working around dartbug.com/35993
and dartbug.com/33441, but bots were failing. I think that was because
of this issue with incorrect tear-off types. We have to fix it before
switching to less generous TypeSystem.

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 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).
