+## Project Workflow
+- Project uses GitHub Actions
+- Use `ktlint -F .` in root folder to format Kotlin code
+- Use SwiftLint for code formatting
+- Always resolve formatting and analyzer errors before completing a task
+- **CRITICAL**: Always run `ktlint -F .` after modifying any Kotlin files before committing
+
+## Pigeon Code Generation
+- Pigeon configuration is in `workmanager_platform_interface/pigeons/workmanager_api.dart`
+- **MUST use melos to regenerate Pigeon files**: `melos run generate:pigeon`
+- ⚠️ **DO NOT** run pigeon directly - always use the melos script for consistency
+- Generated files:
+  - Dart: `workmanager_platform_interface/lib/src/pigeon/workmanager_api.g.dart`
+  - Kotlin: `workmanager_android/android/src/main/kotlin/dev/fluttercommunity/workmanager/pigeon/WorkmanagerApi.g.kt`
+  - Swift: `workmanager_apple/ios/Classes/pigeon/WorkmanagerApi.g.swift`
+- Do not manually edit generated files (*.g.* files)
+- Generated files may have different formatting than dart format - this is expected and handled by exclusion patterns
+
+## Code Formatting Configuration
+- `.editorconfig` in root folder configures ktlint to ignore Pigeon-generated Kotlin files
+- `.swiftlint.yml` in root folder excludes Pigeon-generated Swift files from linting
+
+## GitHub Actions Configuration
+- Format checks: `.github/workflows/format.yml`
+  - Runs dart format, ktlint, and SwiftLint
+- Tests: `.github/workflows/test.yml`
+  - `test`: Runs Dart unit tests
+  - `native_ios_tests`: Runs iOS native tests with xcodebuild
+  - `native_android_tests`: Runs Android native tests with Gradle
+  - `drive_ios`: Runs Flutter integration tests on iOS simulator
+  - `drive_android`: Runs Flutter integration tests on Android emulator
+
+## Testing Strategy & Preferences
+- **Focus on business logic**: Test unique platform implementation logic, not Pigeon plumbing
+- **Trust third-party components**: Consider Pigeon a trusted component - don't test its internals
+- **Platform-specific behavior**: Test what makes each platform unique (Android WorkManager vs iOS BGTaskScheduler)
+- **Avoid channel mocking**: Don't mock platform channels unless absolutely necessary
+- **Test unsupported operations**: Verify platform-specific UnsupportedError throwing
+- **Integration over unit**: Prefer integration tests for complete platform behavior validation
+
+## Test Execution
+- Run all tests: `flutter test` (from root or individual package)
+- Android tests: `cd workmanager_android && flutter test`
+- Apple tests: `cd workmanager_apple && flutter test`
+- Native Android tests: `cd example/android && ./gradlew :workmanager_android:test`
+- Native iOS tests: `cd example/ios && xcodebuild test -workspace Runner.xcworkspace -scheme Runner -destination 'platform=iOS Simulator,name=iPhone 16,OS=latest'`
+- Always build example app before completing: `cd example && flutter build apk --debug && flutter build ios --debug --no-codesign`
+
+## Pigeon Migration Status
+- ✅ Migration to Pigeon v22.7.4 completed successfully
+- ✅ All platforms (Android, iOS) migrated from MethodChannel to Pigeon
+- ✅ Unit tests refactored to focus on platform-specific business logic
+- ✅ Code formatting and linting properly configured for generated files
+- ✅ All tests passing: Dart unit tests, native Android tests, native iOS tests
+- ✅ Example app builds successfully for both Android APK and iOS app
+
+## Documentation Preferences
+- Keep summaries concise - don't repeat completed tasks in status updates
+- Focus on current progress and next steps
+- Document decisions and architectural choices
+
+## CHANGELOG Management
+- Document improvements in CHANGELOG.md files immediately when implemented
+- Use "Future" as the version header for unreleased changes (standard open source practice)
+- Keep entries brief and focused on user-facing impact
+- Relevant files: workmanager/CHANGELOG.md, workmanager_android/CHANGELOG.md, workmanager_apple/CHANGELOG.md
+
+## GitHub Actions - Package Analysis
+- The `analysis.yml` workflow runs package analysis for all packages
+- It performs `flutter analyze` and `dart pub publish --dry-run` for each package
+- The dry-run validates that packages are ready for publishing
+- Common issues that cause failures:
+  - Uncommitted changes in git (packages should be published from clean state)
+  - Files ignored by .gitignore but checked into git (use .pubignore if needed)
+  - Modified files that haven't been committed
+- Always ensure all changes are committed before pushing to avoid CI failures
+
+## GitHub Actions - Formatting Issues
+- The `format.yml` workflow runs formatting checks
+- ❌ **Important Discovery**: `analysis_options.yml formatter.exclude` does NOT prevent `dart format` from formatting files
+- ✅ **FIXED**: Updated CI workflow to use `find` command to exclude .g.dart files:
+  ```bash
+  find . -name "*.dart" ! -name "*.g.dart" ! -path "*/.*" -print0 | xargs -0 dart format --set-exit-if-changed
+  ```
+- **Root Issue**: `dart format` ignores analysis_options.yml exclusions and will always format ALL Dart files
+- **Solution**: Filter files before passing to dart format to exclude generated files
+- The `analysis_options.yml` exclusions only affect static analysis, not formatting

+## Code Generation
+
+This project uses [Pigeon](https://pub.dev/packages/pigeon) for type-safe platform channel communication. If you modify the platform interface:
+
+**⚠️ IMPORTANT**: Always use melos to regenerate Pigeon files:
+
+```bash
+melos run generate:pigeon
+```
+
+**DO NOT** run pigeon directly - always use the melos script for consistency.
+
+## Running the example

 Now you should be able to run example project
