dart_code_quality 0.3.0

A collection of analyzer rules for Dart and Flutter development.

0.3.0

• Performance improvements
• // ignore: and // ignore_for_file: directives now work correctly in the analyzer plugin

0.2.0

Flutter

• avoid-missing-controller: Accept onChanged, add EditableText
• avoid-single-child-column-or-row: Check Flex and Wrap
• avoid-unnecessary-setstate: Flag setState in build
• prefer-center-over-align: Flag Align() with no alignment
• avoid-flexible-outside-flex: Remove Wrap from valid parents
• use-setstate-synchronously: Support context.mounted
• avoid-mounted-in-setstate: Support context.mounted

Riverpod

• use-ref-and-state-synchronously: Support context.mounted/ref.mounted

Config System (Breaking)

• Rules are opt-in: off by default, enabled via recommended.yaml or explicit config
• Config follows include: directives (including package: URIs)
• Plugin and standalone produce identical results
• Rules read config per-file at check time, not from CWD at startup
• Removed fromOptions constructors from all configurable rules

Testing

• Parity test suite: 10 fixtures verifying dart analyze and dcq agreement
• All 389 rules reviewed against DCM specs

0.1.0

• Initial public release.
• 375+ lint rules across Common, Flutter, Riverpod, Equatable, Mocktail, Easy Localization, Intl, and Fake Async categories.
• Recommended preset via package:dart_code_quality/recommended.yaml.
• Built on analysis_server_plugin (requires Dart SDK >=3.11.1).
