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:

2. Task 2: Add delete button and confirmation dialog to TaskFormScreen - 6133c97 (feat)

Plan metadata: (docs commit follows)

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
