Move seven more Hints to be StaticWarnings: * ARGUMENT_TYPE_NOT_ASSIGNABLE_TO_ERROR_HANDLER * BODY_MIGHT_COMPLETE_NORMALLY_CATCH_ERROR * BODY_MIGHT_COMPLETE_NORMALLY_NULLABLE * DEPRECATED_EXTENDS_FUNCTION * DEPRECATED_IMPLEMENTS_FUNCTION * DEPRECATED_MIXIN_FUNCTION * DEPRECATED_NEW_IN_COMMENT_REFERENCE This requires allowing these warnings to be reported in language tests without being expected. Also, observatory now must comply with BODY_MIGHT_COMPLETE_NORMALLY_NULLABLE (or we could ignore the diagnostic).

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).
Dart is free and open source.
