Phase 8: Task Delete Verification Report
Phase Goal: Users can remove tasks they no longer need, with smart preservation of completion history for future statistics Verified: 2026-03-18T20:30:00Z Status: passed Re-verification: No — initial verification
Goal Achievement
Observable Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | Active tasks appear in all views (calendar, room task lists, daily plan) | VERIFIED | All 4 DAOs filter isActive=true; 15 query sites confirmed across tasks_dao.dart, calendar_dao.dart, daily_plan_dao.dart, rooms_dao.dart |
| 2 | Deactivated tasks are hidden from all views | VERIFIED | isActive.equals(true) present on all 6 CalendarDao queries, all 3 DailyPlanDao queries, watchTasksInRoom, getOverdueTaskCount, and watchRoomWithStats |
| 3 | Hard delete removes task and completions from DB entirely | VERIFIED | deleteTask in tasks_dao.dart uses a transaction to delete completions then task; test "hard deleteTask still removes task and its completions" passes |
| 4 | Soft delete sets isActive to false without removing data | VERIFIED | softDeleteTask updates isActive: Value(false) only; test "softDeleteTask sets isActive to false without removing the task" passes — row count stays 1, isActive == false |
| 5 | Existing tasks default to active after migration | VERIFIED | BoolColumn.withDefault(const Constant(true)) on Tasks table; from == 2 migration block calls m.addColumn(tasks, tasks.isActive) which applies the default to existing rows |
| 6 | User sees a red delete button at the bottom of the task edit form | VERIFIED | FilledButton.icon with backgroundColor: theme.colorScheme.error inside if (widget.isEditing) block in task_form_screen.dart lines 207-218 |
| 7 | Tapping delete shows a confirmation dialog before any action | VERIFIED | _onDelete() calls showDialog<bool> with AlertDialog containing title l10n.taskDeleteConfirmTitle, message l10n.taskDeleteConfirmMessage, cancel TextButton, and error-colored confirm FilledButton |
| 8 | Confirming delete routes to hard or soft delete based on completion history | VERIFIED | smartDeleteTask in task_providers.dart calls getCompletionCount and branches: deleteTask if 0, softDeleteTask if >0 |
| 9 | After deletion the user is navigated back to the room task list | VERIFIED | _onDelete() calls context.pop() after awaiting smartDeleteTask; guarded by if (mounted) check |

Required Artifacts
| Artifact | Expected | Status | Details |
|---|---|---|---|
lib/core/database/database.dart |
isActive BoolColumn, schema v3, migration |
VERIFIED | Line 38-39: BoolColumn get isActive => boolean().withDefault(const Constant(true))();; schemaVersion => 3; from == 2 block calls m.addColumn(tasks, tasks.isActive) |
lib/features/tasks/data/tasks_dao.dart |
softDeleteTask, getCompletionCount, isActive filter on queries |
VERIFIED | Both methods present (lines 115-128); watchTasksInRoom and getOverdueTaskCount filter by isActive.equals(true) |
lib/features/home/data/calendar_dao.dart |
isActive=true filter on all 6 queries |
VERIFIED | All 6 methods confirmed: watchTasksForDate (l32), getTaskCount (l56), watchTasksForDateInRoom (l76), watchOverdueTasks (l105), watchOverdueTasksInRoom (l139), getTaskCountInRoom (l164) |
lib/features/home/data/daily_plan_dao.dart |
isActive=true filter on all 3 queries |
VERIFIED | watchAllTasksWithRoomName (l20), getOverdueAndTodayTaskCount (l44), getOverdueTaskCount (l57) — all confirmed |
lib/features/rooms/data/rooms_dao.dart |
isActive=true filter in watchRoomWithStats task query |
VERIFIED | Line 47-49: t.roomId.equals(room.id) & t.isActive.equals(true) |
lib/features/tasks/presentation/task_providers.dart |
smartDeleteTask method using getCompletionCount |
VERIFIED | Lines 94-102: method exists, branches on completion count to deleteTask or softDeleteTask |
lib/features/tasks/presentation/task_form_screen.dart |
Delete button and confirmation dialog in edit mode; uses taskDeleteConfirmTitle |
VERIFIED | Lines 204-218 (button), lines 471-507 (_onDelete method); taskDeleteConfirmTitle at line 476 |
test/features/tasks/data/tasks_dao_test.dart |
Tests for softDeleteTask, getCompletionCount, isActive filtering |
VERIFIED | 6 new tests present and all 13 tests in file pass |
Key Link Verification

Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
|---|---|---|---|---|
| DEL-01 | 08-02-PLAN.md | User can delete a task from the task edit form via a clearly visible delete action | SATISFIED | Red FilledButton.icon with Icons.delete_outline at bottom of edit form, gated on widget.isEditing |
| DEL-02 | 08-01-PLAN.md | Hard delete removes task with no completions from DB entirely | SATISFIED | deleteTask cascade + smartDeleteTask routes to it when getCompletionCount == 0 |
| DEL-03 | 08-01-PLAN.md | Deleting a task with completions deactivates it (soft delete) | SATISFIED | softDeleteTask sets isActive=false; all DAO queries filter by isActive=true so task disappears from views |
| DEL-04 | 08-02-PLAN.md | User sees a confirmation before deleting/deactivating | SATISFIED | _onDelete shows AlertDialog with cancel and confirm actions; action only proceeds when confirmed == true |
All 4 requirements from REQUIREMENTS.md Phase 8 are SATISFIED. No orphaned requirements found.
Anti-Patterns Found
None. No TODOs, FIXMEs, placeholder returns, or stub implementations found in any modified files.
Human Verification Required
1. Delete button visual appearance
Test: Open the app, navigate to a room, tap any task to open the edit form, scroll to the bottom. Expected: A full-width red button labeled "Loschen" (with umlaut) appears below the history row, separated by a divider. Button does not appear when creating a new task. Why human: Visual layout, color rendering, and scroll behavior cannot be verified programmatically.
2. Confirmation dialog flow
Test: Tap the delete button. Tap "Abbrechen" (cancel). Expected: Dialog dismisses, form remains open, task is unchanged. Why human: Dialog dismissal behavior and state preservation requires manual interaction.
3. Smart delete — task with no completions (hard delete)
Test: Create a fresh task (never completed). Open it, tap delete, confirm. Expected: Task disappears from the room list immediately. Navigated back to room task list. Why human: End-to-end flow requires running app with real navigation and reactive provider updates.
4. Smart delete — task with completions (soft delete)
Test: Complete a task at least once. Open it, tap delete, confirm. Expected: Task disappears from all views (room list, calendar, daily plan). Navigation returns to room. Task remains in DB (invisible to user but present for future statistics). Why human: Requires verifying absence from multiple views and confirming data is preserved in DB — combination of UI behavior and DB state inspection.
Gaps Summary
No gaps. All must-haves verified.
