Changelog

[Unreleased] — 2026-02-25

Architecture

  • Decomposed file_comparison_view.dart from 3,819 lines to ~2,946 lines (23% reduction) by extracting:
    • DiffListItem widget (lib/presentation/widgets/diff/diff_list_item.dart)
    • ExportService (lib/core/services/export_service.dart)
    • FilePickerDropZone widget (lib/presentation/widgets/file_picker_drop_zone.dart)
    • PlatformTaskbarService (lib/core/services/platform_taskbar_service.dart) — Windows taskbar is now behind a clean abstraction
  • Moved history recording logic from the presentation layer into ComparisonBloc where it belongs
  • Split SettingsBloc (1,772 lines, 104 events) into three focused sub-BLoCs:
    • AppearanceBloc — theme mode, accent color, diff colors, fonts
    • AiServicesBloc — API keys, model selection, AI temperature, translation memory
    • FileHandlingBloc — encoding, CSV delimiter, BOM, backup, export format
  • Declared previously-transitive dependencies (path_provider, provider) explicitly in pubspec.yaml
  • Removed unused macos_ui dependency
  • Extracted _computeColorPalette() to consolidate duplicated HSL color computation across 4 theme factories
  • Moved GitBloc mutable fields (_cachedBranches, _cachedCommits, etc.) into Freezed state

State Management

  • Added extends Equatable with proper props to 6 event base classes: ComparisonEvent, GitEvent, HistoryEvent, ProgressEvent, TranslationEvent, FileWatcherEvent
  • Fixed context.watch<SettingsBloc>() calls inside non-build helper methods — state is now read once at the top of build() and passed as parameters
  • Added buildWhen predicate to BlocBuilder<SettingsBloc> in user_onboarding_checklist.dart
  • Removed dead code: duplicate if (projectSettings?.defaultAiModel != null) block in settings_state.dart

Accessibility

  • Added Semantics(button: true, label: ...) to InkWell-based interactive elements (theme toggle, animated preview entries)
  • Converted _ActionIconButton from InkWell+Tooltip to proper IconButton throughout the diff table
  • Added tooltip: labels to 13 icon-only buttons (pagination controls, close buttons, clear search, back, delete glossary, toggle AI params)
  • Added non-color diff status indicators ("+", "-", "~", "=") to diff list items and diff table rows — satisfies WCAG SC 1.4.1
  • Raised default accent color from 0xFF7B61FF to 0xFF9B8FFF for better contrast on dark backgrounds (~4.6:1 ratio)
  • Fixed blank tooltip: '' on "More actions" PopupMenuButton
  • Added label: parameter to AI temperature Slider
  • Wrapped color swatches in Semantics(label: 'Color swatch: #RRGGBB') in appearance settings
  • Added colorblind-friendly diff color preset (blue/orange/teal) to the first-run wizard
  • Removed semanticsEnabled: false from 8 test cases

Testing

  • Raised test coverage from ~12% toward meaningful coverage of all critical paths
  • 259 tests passing, 0 failures, 0 skipped (previously 182 passing, 3 failing, 7 skipped)
  • New test files:
    • test/helpers/mocks.dart — shared mock library used across all test files
    • test/business_logic/blocs/comparison_bloc_test.dart (10 tests)
    • test/business_logic/blocs/translation_bloc_test.dart (6 tests)
    • test/business_logic/blocs/git_bloc_test.dart (7 tests)
    • test/data/parsers/arb_parser_test.dart (7 tests)
    • test/data/parsers/csv_parser_test.dart (9 tests)
    • test/data/parsers/properties_parser_test.dart (7 tests)
    • test/data/parsers/resx_parser_test.dart (7 tests)
  • Fixed settings_bloc_test.dart timing issues (replaced Future.delayed + skip: with wait: and seed:)
  • Fixed and un-skipped ComparisonResultDialog test and ComparisonSettingsCard test group
  • Replaced expect(true, isTrue) placeholder in widget_test.dart with real tests

Code Quality

  • Replaced 57 deprecated .withOpacity(X) calls with .withValues(alpha: X) across 6 files
