Because non-late field initializers in classes with primary constructors have access to the parameters of the primary constructor, field initializers are be moved to the initializer list of this constructor, so the generated AST will no access these parameters out of scope. This CL add an exception to this rule for mixin classes: In the non-erroneous cases, these can't have parameters, so the field initializers can stay in the field declaration. This is done to ensure that mixin transformation can simply clone the mixin class fields, instead of having to fetch the initializer from the initializer list of the constructor. For mixin classes with parameters in the primary constructor, which is an erroneous case, the initializers are moved to the constructor like for other primary constructors to avoid generating an AST where the parameters are accessed out of scope.

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).
