# Phase 8 Plan 02: Task Delete UI Summary
|
|
|
|
**Red delete button with confirmation dialog in task edit form: hard-deletes unused tasks, soft-deletes tasks with completion history**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-03-18T19:59:37Z
|
|
- **Completed:** 2026-03-18T20:02:05Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 2
|
|
|
|
## Accomplishments
|
|
|
|
- Added `smartDeleteTask` to `TaskActions` Riverpod notifier — checks completion count and routes to DAO `deleteTask` (hard) or `softDeleteTask` (soft)
|
|
- Added red `FilledButton.icon` with error colorScheme at bottom of task edit form, separated from history section by a `Divider`
|
|
- Added `_onDelete` confirmation dialog using existing `taskDeleteConfirmTitle`, `taskDeleteConfirmMessage`, `taskDeleteConfirmAction`, and `cancel` l10n strings
|
|
- All 144 tests pass, `dart analyze --fatal-infos` clean
|
|
|
|
## Task Commits

Each task was committed atomically:
|
|
|
|
1. **Task 1: Add smartDeleteTask to TaskActions provider** - `1b1b981` (feat)
|
|
2. **Task 2: Add delete button and confirmation dialog to TaskFormScreen** - `6133c97` (feat)
|

|
|
## Files Created/Modified
|
|
|
|
- `lib/features/tasks/presentation/task_providers.dart` - Added `smartDeleteTask` method to `TaskActions` class
|
|
- `lib/features/tasks/presentation/task_providers.g.dart` - Regenerated by build_runner (no functional changes)
|
|
- `lib/features/tasks/presentation/task_form_screen.dart` - Added delete button in edit mode and `_onDelete` async method
|
|
|
|
## Decisions Made
|
|
|
|
- `smartDeleteTask` kept separate from `deleteTask` to preserve the existing hard-delete path used for room cascade deletes and any other callers
|
|
- Delete button placed after history ListTile, inside the `if (widget.isEditing)` block, so it never appears in create mode
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
|
|
None.
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- Complete delete flow is working: task edit form -> red delete button -> confirmation dialog -> smart delete -> pop back to room task list
|
|
- Soft-deleted tasks (isActive=false) are already filtered from all views (implemented in Plan 01)
|
|
- Phase 08-task-delete is fully complete
