Code Quality Review

Changes

Removes two lines from README.md that recommended running flutter pub run custom_lint for Flutter projects. The flutter pub run command is deprecated in favor of dart run, which already works for both Dart and Flutter projects and is documented immediately above the removed lines.

Quality Assessment

Positives:

• Correct removal. flutter pub run has been deprecated since Flutter 3.12+ / Dart 3.1+ and emits a deprecation warning as shown in the PR description.
• dart run custom_lint works universally for both Dart-only and Flutter projects, so the Flutter-specific instruction was redundant even before the deprecation.
• Minimal, surgical change -- exactly the right scope for a docs fix.
• No trailing whitespace or formatting issues introduced.

No concerns. This is a straightforward documentation correction.

Verdict

APPROVE -- Clean, correct removal of deprecated guidance. The remaining dart run custom_lint instruction covers both Dart and Flutter projects.

Fork Maintainer Review (dart_custom_lint)

Reviewing on behalf of open-runtime/dart_custom_lint fork.

Summary

Removes the deprecated flutter pub run custom_lint instruction from the README. The flutter pub run command has been deprecated in favor of dart run, and using it produces a deprecation warning. The PR removes the two-line note: "If you are working on a Flutter project, run flutter pub run custom_lint instead."

Upstream Status

Open on upstream (invertase/dart_custom_lint), not yet merged. Community contribution by @abraham.

Assessment

Trivially correct. flutter pub run has been deprecated since Flutter 3.12+ / Dart 3.1+. The existing dart run custom_lint instruction already works for both Dart and Flutter projects. Removing the outdated guidance prevents user confusion.

• No risk

Recommendation

SYNC_FROM_UPSTREAM (once merged) -- This is a documentation-only change with zero risk. Will come in naturally when we sync from upstream. Not worth cherry-picking independently given how minor it is.

Compatibility Review (Monorepo Impact)

Reviewer context: We maintain the open-runtime/dart_custom_lint fork, consumed as a workspace member in our Dart monorepo (aot_monorepo).

Monorepo Impact

NONE. This is a README-only change (removes 2 lines). No code, no dependencies, no configuration affected. Our monorepo uses dart run custom_lint exclusively; we do not use flutter pub run.

Dependency Concerns

None. Documentation-only change.

Recommendation

MERGE -- Clean removal of deprecated guidance. dart run custom_lint works for both Dart and Flutter projects. No monorepo compatibility concerns whatsoever.
