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
