Move another batch of analyzer tests away from offset-based assertErrorsInCode() expectations. Put expected diagnostics and context messages directly in the source snippets instead, including multi-file cases that need context markers in supporting files. This keeps each diagnostic expectation next to the code that produces it, making the tests easier to read and less fragile when surrounding code changes. It also removes now-unused diagnostic imports and helper parameters that were only needed for explicit ExpectedDiagnostic lists. Update the diagnostic expectation utilities so stripping generated marker lines preserves the retained source lines correctly.

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).
