Added #

• Part file analysis - Full support for part and part of directives with zero false positives
• Cross-part references - Correctly tracks class usage across part boundaries
• Code generation support - Works with Realm, Freezed, and other generators
• Warning system - Non-fatal warnings for part file issues with actionable suggestions
• 122 new tests - Comprehensive part file test coverage (208 total tests)

Fixed #

• Realm $ClassName models no longer falsely reported when using --include-generated
• Freezed generated classes correctly detected across part boundaries
• Generated code in part files properly analyzed

Performance #

• <0.5% regression on part-heavy projects (actually -0.1% improvement with caching)
• 100% precision and recall maintained

Initial Release #

Production-ready dead code analyzer for Dart & Flutter with 100% precision and 100% recall.

Core Features #

• Detects unused: Classes, abstract classes, mixins, enums, extensions
• Smart analysis: Tracks instantiation, type annotations, inheritance, generics, static methods
• Flexible ignoring: @keepUnused annotation, config file patterns, CLI exclusions
• Generated code aware: Auto-excludes *.g.dart, *.freezed.dart, *.realm.dart
• Fast: <5s for 10k LOC, <30s for 50k LOC
• Cross-platform: macOS, Linux, Windows

CLI Options #

--path <path>              # Paths to analyze (default: lib/)
--exclude <pattern>        # Glob patterns to exclude
--include-tests            # Analyze test files
--include-generated        # Analyze generated code
--ignore-analysis-options  # Skip analysis_options.yaml
--verbose                  # Show detailed progress
--quiet                    # Show results only

Configuration #

Create flutter_prunekit.yaml:

exclude:
  - 'lib/legacy/**'
  - '**/old_*.dart'

ignore_annotations:
  - 'deprecated'
  - 'experimental'

Quality Metrics #

Known Limitations #

• Classes used via dynamic may not be tracked (warning issued)
• Reflection/mirrors not detected
• Platform-specific imports may need @keepUnused

Installation #

# Add to project
dart pub add --dev flutter_prunekit

# Or install globally
dart pub global activate flutter_prunekit

Usage #

# Basic analysis
dart run flutter_prunekit

# With options
dart run flutter_prunekit --path lib --exclude 'lib/legacy/**' --verbose
