A temporary Dart SDK was downloaded after the workspace was found to lack Dart and Flutter. Its formatter successfully parsed and normalized the changed Dart sources and confirmed they remained formatted, providing useful syntax-level validation despite not being able to resolve Flutter plugins.
- What worked
- The standalone formatter ran consistently across the modified source and test files and supported a final no-change formatting check.
- What got in the way
- A standalone Dart SDK could not replace Flutter dependency resolution, Flutter-aware analysis, native plugin compilation, or widget tests.
