Konstantin Shcheglov 5252e5e3d3 CQ. Remove assertErrorsInFile2(), use resolveFilesWithDiagnostics().
Add helpers that resolve non-test files using the same inline diagnostic
expectation format as resolveTestCodeWithDiagnostics.
resolveFileWithDiagnostics handles a single file, while
resolveFilesWithDiagnostics writes all related files before resolving
any of them.

Add multi-file diagnostic expectation generation so context messages in
one file can be referenced from diagnostics reported in another. Teach
expectation updating how to target values in a files-to-code map using
per-entry intra-invocation ids.

Remove assertErrorsInFile2 and migrate diagnostics tests from
hand-written ExpectedError offsets to inline markers. This keeps the
diagnostic range, code, message, and cross-file context next to the code
under test, and makes expectation updates reusable for library and part
tests.

Initialize strong-mode type assertions from resolveFile so callers that
resolve files other than testFile get the same setup.

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).
