# 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- Some plan specifications referenced outdated API patterns (flutter_local_notifications positional parameters removed in v20+) — research needs to verify exact current API signatures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 `mounted` guards
|
|
- Provider override pattern in widget tests for database isolation
|
|
|
|
### Key Lessons
|
|
1. Research phase should verify exact current package API signatures — breaking changes between major versions cause plan deviations
|
|
2. Drift + riverpod_generator type incompatibility is a known issue — plan for manual providers from the start when using drift
|
|
3. Verification gates add minimal time (~2 min) but catch integration issues — keep them for all phases
|
|
4. 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
