From 7cf1dae6c1a11328d4f8d93f0f24945280adda17 Mon Sep 17 00:00:00 2001 From: "engine-labs-app[bot]" <140088366+engine-labs-app[bot]@users.noreply.github.com> Date: Thu, 30 Oct 2025 14:56:32 +0000 Subject: [PATCH] feat(caching, qr): implement local caching, QR scanner workflow, and cache management UI Adds robust local animation caching with TTL and size policies, full QR scanner workflow, cache management UI with status, and thorough unit/widget tests. All features support offline fallback and follow clean architecture. - Implements custom file-based cache service with automatic cleanup (TTL & size) - Adds QR scanner UI/logic, with parsing for JSON/ID/URL animated codes and scan history - Adds state management and UI for cache status, individual item actions, and warnings - Provides docs and tests for cache, QR service, use cases, and UI No breaking changes. User experience improved with offline support and clear cache controls. --- IMPLEMENTATION_SUMMARY.md | 254 ++++++++++++ docs/CACHING_AND_QR_GUIDE.md | 338 ++++++++++++++++ docs/TESTING_GUIDE.md | 254 ++++++++++++ lib/core/di/injection_container.config.dart | 95 +++++ lib/core/di/injection_container.dart | 32 ++ lib/core/router/app_router.dart | 20 +- .../animation_remote_data_source.dart | 102 +++++ .../animation_repository_impl.dart | 87 ++++ .../repositories/cache_repository_impl.dart | 85 ++++ lib/data/repositories/qr_repository_impl.dart | 33 ++ lib/data/services/cache_service.dart | 156 ++++++++ lib/data/services/qr_service.dart | 107 +++++ lib/domain/entities/animation.dart | 73 ++++ lib/domain/entities/cache_info.dart | 54 +++ lib/domain/entities/qr_code.dart | 45 +++ .../repositories/animation_repository.dart | 11 + lib/domain/repositories/cache_repository.dart | 12 + lib/domain/repositories/qr_repository.dart | 8 + lib/domain/usecases/clear_cache_usecase.dart | 22 + .../usecases/download_animation_usecase.dart | 22 + .../usecases/get_cache_info_usecase.dart | 20 + .../get_cached_animations_usecase.dart | 22 + lib/domain/usecases/scan_qr_code_usecase.dart | 22 + lib/l10n/app_en.arb | 29 +- lib/presentation/pages/ar/ar_page.dart | 4 +- .../pages/cache/cache_management_page.dart | 378 ++++++++++++++++++ lib/presentation/pages/media/media_page.dart | 206 +++++++--- .../pages/qr/qr_history_page.dart | 246 ++++++++++++ .../pages/qr/qr_scanner_page.dart | 256 ++++++++++++ .../providers/animation_provider.dart | 145 +++++++ .../providers/cache_provider.dart | 159 ++++++++ lib/presentation/providers/qr_provider.dart | 175 ++++++++ .../widgets/cache_status_widget.dart | 236 +++++++++++ .../widgets/qr_scanner_overlay.dart | 173 ++++++++ pubspec.yaml | 2 + test/unit/cache_service_test.dart | 123 ++++++ test/unit/qr_service_test.dart | 161 ++++++++ test/unit/usecases_test.dart | 157 ++++++++ test/widget/cache_status_widget_test.dart | 200 +++++++++ 39 files changed, 4469 insertions(+), 55 deletions(-) create mode 100644 IMPLEMENTATION_SUMMARY.md create mode 100644 docs/CACHING_AND_QR_GUIDE.md create mode 100644 docs/TESTING_GUIDE.md create mode 100644 lib/core/di/injection_container.config.dart create mode 100644 lib/data/datasources/animation_remote_data_source.dart create mode 100644 lib/data/repositories/animation_repository_impl.dart create mode 100644 lib/data/repositories/cache_repository_impl.dart create mode 100644 lib/data/repositories/qr_repository_impl.dart create mode 100644 lib/data/services/cache_service.dart create mode 100644 lib/data/services/qr_service.dart create mode 100644 lib/domain/entities/animation.dart create mode 100644 lib/domain/entities/cache_info.dart create mode 100644 lib/domain/entities/qr_code.dart create mode 100644 lib/domain/repositories/animation_repository.dart create mode 100644 lib/domain/repositories/cache_repository.dart create mode 100644 lib/domain/repositories/qr_repository.dart create mode 100644 lib/domain/usecases/clear_cache_usecase.dart create mode 100644 lib/domain/usecases/download_animation_usecase.dart create mode 100644 lib/domain/usecases/get_cache_info_usecase.dart create mode 100644 lib/domain/usecases/get_cached_animations_usecase.dart create mode 100644 lib/domain/usecases/scan_qr_code_usecase.dart create mode 100644 lib/presentation/pages/cache/cache_management_page.dart create mode 100644 lib/presentation/pages/qr/qr_history_page.dart create mode 100644 lib/presentation/pages/qr/qr_scanner_page.dart create mode 100644 lib/presentation/providers/animation_provider.dart create mode 100644 lib/presentation/providers/cache_provider.dart create mode 100644 lib/presentation/providers/qr_provider.dart create mode 100644 lib/presentation/widgets/cache_status_widget.dart create mode 100644 lib/presentation/widgets/qr_scanner_overlay.dart create mode 100644 test/unit/cache_service_test.dart create mode 100644 test/unit/qr_service_test.dart create mode 100644 test/unit/usecases_test.dart create mode 100644 test/widget/cache_status_widget_test.dart diff --git a/IMPLEMENTATION_SUMMARY.md b/IMPLEMENTATION_SUMMARY.md new file mode 100644 index 0000000..d7ebfa5 --- /dev/null +++ b/IMPLEMENTATION_SUMMARY.md @@ -0,0 +1,254 @@ +# Caching and QR Access - Implementation Summary + +## Overview + +This implementation provides a comprehensive caching and QR scanner system for the Flutter AR application, following clean architecture principles with proper separation of concerns. + +## โœ… Completed Features + +### 1.
