# Phase 9 Plan 01: Task Creation UX — Frequency Picker Rework Summary
|
|
|
|
**4 shortcut chips (Täglich/Wöchentlich/Alle 2 Wochen/Monatlich) + always-visible freeform picker replacing the 10-chip grid with hidden Custom mode**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-03-18T21:43:24Z
|
|
- **Completed:** 2026-03-18T21:45:30Z
|
|
- **Tasks:** 1 (+ 1 auto-approved checkpoint)
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- Replaced 10-chip preset grid and hidden "Benutzerdefiniert" mode with 4 shortcut chips + always-visible freeform picker
|
|
- Implemented bidirectional sync: tapping a chip populates the picker; editing the picker recalculates chip highlight
|
|
- Simplified _resolveFrequency() to read exclusively from the picker (single source of truth), using named IntervalTypes for canonical values
|
|
- Edit mode correctly loads all 8 IntervalType values (daily, everyNDays, weekly, biweekly, monthly, everyNMonths, quarterly, yearly) into the picker and highlights the matching shortcut chip where applicable
|

## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Rework frequency picker — shortcut chips + freeform picker** - `8a0b69b` (feat)
|
|
2. **Task 2: Verify frequency picker UX** - auto-approved (checkpoint:human-verify, auto_advance=true)
|
|
|
|
**Plan metadata:** (docs commit follows)
|
|
|
|
## Files Created/Modified
|
|
- `lib/features/tasks/presentation/task_form_screen.dart` - Reworked frequency picker: removed _selectedPreset and _isCustomFrequency fields; added _ShortcutFrequency enum and _activeShortcut state; replaced _buildFrequencySelector() with shortcut chips + always-visible picker; renamed _buildCustomFrequencyInput to _buildFrequencyPickerRow with bidirectional sync; simplified _resolveFrequency() to picker-only
|
|
- `lib/l10n/app_de.arb` - Added frequencyShortcutDaily/Weekly/Biweekly/Monthly keys
|
|
- `lib/l10n/app_localizations.dart` - Regenerated to include new shortcut string getters
|
|
- `lib/l10n/app_localizations_de.dart` - Regenerated with German translations (Täglich, Wöchentlich, Alle 2 Wochen, Monatlich)
|
|
|
|
## Decisions Made
|
|
- Picker is single source of truth: _resolveFrequency() reads from _customIntervalController + _customUnit always, regardless of which chip is highlighted
|
|
- _ShortcutFrequency enum with toPickerValues() and static fromPickerValues() cleanly handles bidirectional sync without manual if-chain mapping in each callback
|
|
- Named IntervalTypes (daily/weekly/biweekly/monthly) used for canonical values (e.g., weekly has days=1, biweekly has days=14) matching existing DB records; only everyNDays used for 3+ weeks
|
|
- Quarterly (3 months) and yearly (12 months) round-trip correctly: loaded as "3 Monate" / "12 Monate" in picker with no chip highlighted
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None.
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Frequency picker rework complete; TaskFormScreen is ready for further UX improvements
|
|
- All 144 existing tests pass, dart analyze is clean
|
|
- No changes to frequency.dart, no DB migration, no new screens
