mini_types: introduce new classes for special built-in types. New classes are introduced into the "mini_types" representation to represent `dynamic`, `FutureOr<T>`, `Never`, `Null`, `void`, and the "invalid" type. Previously, these were all represented simply using `PrimaryType`. Introducing new classes for these types makes the "mini_types" representation more consistent with the representations used by the analyzer and the front end. Since the "mini_types" representation is used solely for unit testing the shared logic in the `_fe_analyzer_shared` package, it's hard to justify unnecessary differences between it and the analyzer and front end representations; these differences just make it harder to effectively share code.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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.
