New Features #

• feat(rules): add avoid_relative_barrel_imports rule to encourage package imports over relative imports for cross-feature barrel files
• feat(rules): add avoid_ui_framework_in_logic rule to enforce framework independence in domain/data layers
• feat(rules): add avoid_improper_layer_import rule to enforce clean architecture layer boundaries (UI → Data → Domain)
• feat(quickfix): add ConvertToPackageImport quick fix to automatically convert relative barrel imports to package imports
• feat(quickfix): add UseLayerSpecificBarrel quick fix to suggest layer-specific barrel imports (e.g., xxx_data.dart instead of xxx.dart)

Improvements #

• perf: significantly improved analysis performance with cached regex patterns and early test file exits
• fix(rules): avoid_self_barrel_import now correctly detects split barrel self-imports and allows cross-layer imports within the same feature
• fix(rules): avoid_improper_layer_import now flags monolithic barrel usage in data/domain layers and suggests split barrels

Breaking Changes #

• BREAKING: removed avoid_barrel_cycle rule due to performance concerns (synchronous file I/O caused 150-1250ms overhead)
  • Use CLI tool instead: dart run barrel_file_lints:check_cycles (detects both immediate and transitive cycles)
  • Integrate into CI/CD for comprehensive cycle detection without impacting real-time analysis

Documentation #

• Add comprehensive documentation for all rules and split barrel architecture
• Add "Setting Up Split Barrel Files" guide to README

• feat(rules): add avoid_cross_feature_barrel_exports rule to ensure barrel files only export from their own feature folder
• feat(cli): add check_cycles CLI tool for detecting circular dependencies (both immediate and transitive: A → B → C → A)
• feat(quickfix): add quick fix to remove cross-feature exports from barrel files
• feat(quickfix): add RemoveSelfBarrelImport quick fix for circular self-imports
• feat(quickfix): add SimplifyRelativePath quick fix for redundant relative paths within same feature
• fix(rules): avoid_self_barrel_import now correctly handles relative imports at different directory depths

• feat(rules): add avoid_self_barrel_import rule to prevent circular dependencies
• feat(rules): extend internal directory detection to include common Flutter/Dart patterns: /services/, /repositories/, /providers/, /bloc/, /cubit/, /notifiers/, /widgets/, /utils/, /config/, /helpers/
• fix(config): analysis_options.yaml now uses root-level plugins: (Dart 3.10+ standard)

• Improved documentation and API coverage

• Improved CI/CD and publishing workflows

• feat: initial stable release
• feat(rules): add avoid_internal_feature_imports rule - features must import other features via barrel files only
• feat(rules): add avoid_core_importing_features rule - core module must not import from feature modules
• feat(quickfix): add quick fix to replace internal import with barrel file import
• feat(quickfix): add quick fix to comment out feature import in core with TODO
• feat: support both naming conventions: feature_xxx/ (underscore) and features/xxx/ (clean architecture)
• feat: support both absolute (package:) and relative (../) imports
• feat: automatically exclude test files from checks
• test: add comprehensive test suite (47 tests across 7 test files)
• ci: add full CI/CD pipeline with GitHub Actions
• docs: add complete documentation and examples
