Deleting tasks

There’s stuff we just don’t want to do!

We can delete a Task on dismiss by wrapping the tile with a Dismissible and calling its delete method:

class TasksScreen extends HookConsumerWidget {
  Widget build(BuildContext context, WidgetRef ref) {
    final state = ref.tasks.watchAll(params: {'_limit': 5}, syncLocal: true);
    final _newTaskController = useTextEditingController();

    if (state.isLoading) {
      return CircularProgressIndicator();
    return RefreshIndicator(
      onRefresh: () =>
          ref.tasks.findAll(params: {'_limit': 5}, syncLocal: true),
      child: ListView(
        children: [
            controller: _newTaskController,
            onSubmitted: (value) async {
              Task(title: value).init(;
          for (final task in state.model)
              key: ValueKey(task),
              direction: DismissDirection.endToStart,
              onDismissed: (_) => task.delete(),
              child: ListTile(
                leading: Checkbox(
                  value: task.completed,
                  onChanged: (value) => task.toggleCompleted().save(),
                title: Text('${task.title} [id: ${}]'),

Hot-reload, swipe left and… they’re gone!
