AST. Expose assignment target read and write resolutions. Add common read and write resolution accessors to AssignmentTarget so clients can inspect assignment semantics without switching on the concrete target kind. Introduce ReadResolution and WriteResolution as shared interfaces for named and indexed operations, and make the existing resolution types implement them. Update analyzer consumers and V1 compatibility logic to use the common accessors, reducing repeated target-kind dispatch while preserving the existing element and type behavior.

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.
