flutter_skill_lints 0.1.0

Analyzer plugin companion for the building-flutter-apps skill's Dart and Flutter guardrails.

flutter_skill_lints

flutter_skill_lints is the companion analyzer plugin for the building-flutter-apps skill. It is a new project inspired by many_lints and exposes Flutter skill diagnostics through one public plugin.

Install the skill for agent guidance:

npx skills add https://github.com/sgaabdu4/building-flutter-apps --skill building-flutter-apps

Install

Add the analyzer plugin to the top-level plugins section in analysis_options.yaml:

plugins:
  flutter_skill_lints:
    version: ^0.1.0
  riverpod_lint: 3.1.4-dev.3

Analyzer plugins are not added to pubspec.yaml. After changing the plugins section, restart the Dart Analysis Server so IDE diagnostics pick up the new plugin configuration.

Rule Surface

The plugin registers:

• 79 additional Dart/Flutter warning rules, 61 fixes, and 1 assist.
• 16 Flutter skill rules, including project config and scanner compatibility rules.

Additional rule diagnostic IDs are preserved for compatibility with existing analysis_options.yaml files. Off-profile BLoC/Cubit, Equatable, destructuring, constant-switch, and style-preference rules are not shipped in the default package surface, so app repos do not need a diagnostics override block for the Flutter skill profile.

Current verified resolution is analysis_server_plugin 0.3.14, analyzer 12.1.0, and analyzer_plugin 0.14.8. Recheck riverpod_lint, analysis_server_plugin, analyzer, and analyzer_plugin before publishing.
