Move augmentation type parameter validation from element binding to the error verifier so that augmentation diagnostics are reported from the same phase as other declaration consistency checks. After verifying that the augmentation has the same number of type parameters as the introductory declaration, compare each written type parameter name against the corresponding introductory fragment and report augmentationTypeParameterName when they differ. Apply the check to augmentations of classes, enums, extensions, extension types, mixins, top-level functions, and methods.

Dart
An approachable, portable, and productive language for high-quality apps on any platform
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).
