Abstract field support: detect when a concrete implementation is missing.

This CL covers two cases: when an abstract field appears in a concrete
class (which we report as CONCRETE_CLASS_WITH_ABSTRACT_MEMBER, just as
we do for abstract methods), and when a concrete class implements a
class with an abstract field, but fails to supply the necessary
concrete implementation(s) (which we report as
NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER_*, just as we do for
abstract methods).

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).
