I'm using Flutter Local Notifications to send a reminder to users every day at a time of their choice. My schedule function in my notification service looks like this:

  Future<void> scheduleDailyNotification(
      DateTime setTime, String title, String body, String payload) async {
    // Setup notification details
    const DarwinNotificationDetails iosNotificationDetails =
        DarwinNotificationDetails(presentAlert: true, presentSound: true);
    const NotificationDetails notificationDetails =
        NotificationDetails(iOS: iosNotificationDetails);

    // Convert to TZDateTime
    final tz.TZDateTime scheduledDate = tz.TZDateTime(
      tz.local,
      setTime.year,
      setTime.month,
      setTime.day,
      setTime.hour,
      setTime.minute,
      setTime.second,
    );

    logger.d('Scheduling notification for: $scheduledDate');
    // Schedule notification
    await _flutterLocalNotificationsPlugin.zonedSchedule(
        0, title, body, scheduledDate, notificationDetails,
        payload: payload,
        uiLocalNotificationDateInterpretation:
            UILocalNotificationDateInterpretation.absoluteTime,
        matchDateTimeComponents: DateTimeComponents.time);
  }

Now this reminder should only be sent if the user did not take a specific action in the app. If the user takes this action, I want to cancel todays notification, but start sending out notifications again tomorrow:

  Future<void> cancelTodaysNotification() async {
    final tz.TZDateTime now = tz.TZDateTime.now(tz.local);
    DateTime setTime = await _getNotificationsTimeFromPrefs();
    final tz.TZDateTime scheduledDate = tz.TZDateTime(
        tz.local, now.year, now.month, now.day, setTime.hour, setTime.minute);

    if (now.isBefore(scheduledDate)) {
      logger.d('Cancelling notification for today');
      await _flutterLocalNotificationsPlugin.cancel(0);

      // Get next valid date and add one day
      final tomorrow =
          _nextInstanceOfTime(setTime).add(const Duration(days: 1));
      await scheduleDailyNotification(tomorrow, _notificationTitle,
          _notificationBody, _notificationPayload);
    }
  }

This does not work because matchDateTimeComponents: DateTimeComponents.time means that the date is ignored. It will just schedule a notification for today again (given that the time is in the future)

Is there a way to cancel today's notification without adding a background process to the app?

One idea I had is to use DateTimeComponents.dayOfWeekAndTime instead of DateTimeComponents.time. If today is Wednesday I could cancel all notifications and then schedule them again for every day except Wednesday. BUT this would mean that from now on no notifications will be sent on Wednesdays...

This seems like a very obvious feature and I hope I'm missing something.
