Project Retrospective
A living document updated after each milestone. Lessons feed forward into future planning.
Milestone: v1.0 — MVP
Shipped: 2026-03-16 Phases: 4 | Plans: 13
What Was Built
- Complete room-based household chore app with auto-scheduling task management
- Daily plan home screen with overdue/today/tomorrow sections and progress tracking
- Bundled German task templates for 14 room types
- Daily summary notifications with configurable time and Android permission handling
- 89 tests covering DAOs, scheduling logic, providers, and widget behavior
What Worked
- Bottom-up phase structure (foundation -> data -> UI -> polish) kept each phase clean with minimal rework
- TDD approach for providers and services caught several issues early (async race conditions, API mismatches)
- Verification gates at the end of Phase 2, 3, and 4 confirmed all requirements before moving on
- Calendar-anchored scheduling with anchor memory was designed right the first time — no rework needed
- ARB localization from Phase 1 meant adding German strings was frictionless throughout
What Was Inefficient
- riverpod_generator InvalidTypeException with drift Task type required workaround (manual StreamProvider) in 3 separate plans — should have been caught in Phase 1 research
- Some plan specifications referenced outdated API patterns (flutter_local_notifications positional parameters removed in v20+) — research needs to verify exact current API signatures
- Phase 4 plan checkboxes in ROADMAP.md weren't updated to [x] by executor — minor bookkeeping gap
Patterns Established
@Riverpod(keepAlive: true)AsyncNotifier with SharedPreferences for persistent settings (ThemeNotifier, NotificationSettingsNotifier)- Manual StreamProvider.family/autoDispose for drift type compatibility
- DailyPlanDao innerJoin pattern for cross-table queries
- ConsumerStatefulWidget for screens with async callbacks requiring
mountedguards - Provider override pattern in widget tests for database isolation
Key Lessons
- Research phase should verify exact current package API signatures — breaking changes between major versions cause plan deviations
- Drift + riverpod_generator type incompatibility is a known issue — plan for manual providers from the start when using drift
- Verification gates add minimal time (~2 min) but catch integration issues — keep them for all phases
- Progressive disclosure (AnimatedSize) is a clean pattern for conditional settings UI
Cost Observations
- Model mix: orchestrator on opus, researchers/planners/executors/checkers on sonnet
- Total execution: ~1.3 hours for 13 plans across 4 phases
- Notable: Verification gates averaged 2 min — very efficient for the confidence they provide
