I am trying to implement the local notification in flutter where user set the notification coming days like coming in sunday, monday and tuesday , and then user set the time range like between 4-5pm and finally user set the interval of time in which notification/alert comes like every 5 minutes. So the notification should come in selected days only and selected time range and in every interval time gap.

    final Random random = Random();
    int randomNumber = random.nextInt(100);
    final DateTime now = DateTime.now();

    DateTime startDate = convertTimeOfDayToDateTime(startTime);
    DateTime endDate = convertTimeOfDayToDateTime(endTime);

    // Loop through each day of the week
    for (int i = 0; i < 7; i++) {
      // Calculate the next occurrence of this day
      DateTime nextOccurrence =
          now.add(Duration(days: (i - now.weekday + 7) % 7));
      // Check if the day is selected
      if (_selectedDays[nextOccurrence.weekday % 7]) {
        DateTime notificationStart = DateTime(
            nextOccurrence.year,
            nextOccurrence.month,
            nextOccurrence.day,
            startDate.hour,
            startDate.minute);
        DateTime notificationEnd = DateTime(
            nextOccurrence.year,
            nextOccurrence.month,
            nextOccurrence.day,
            endDate.hour,
            endDate.minute);

        // Only schedule if the start date is in the future
        if (notificationStart.isAfter(now)) {
          int totalDuration = notificationEnd.millisecondsSinceEpoch -
              notificationStart.millisecondsSinceEpoch;
          int numberOfIntervals = totalDuration ~/ 60000;

          logger.d(
              'Scheduling notifications for: $nextOccurrence (day ${nextOccurrence.weekday})');

          await scheduleNotificationsForDay(notificationStart,
              numberOfIntervals, randomNumber, 60000, notificationEnd);
        }
      } else {
        logger.d(
            'Skipping notifications for: $nextOccurrence (day ${nextOccurrence.weekday})');
      }
    }
  }

  DateTime convertTimeOfDayToDateTime(TimeOfDay timeOfDay) {
    final now = DateTime.now();
    return DateTime(
        now.year, now.month, now.day, timeOfDay.hour, timeOfDay.minute);
  }

  tz.TZDateTime _convertToTZDateTime(DateTime dateTime) {
    final tzLocation = tz
        .local; // Use the appropriate timezone or tz.getLocation('Your/Timezone')
    return tz.TZDateTime.from(dateTime, tzLocation);
  }

  Future<void> scheduleNotificationsForDay(DateTime start,
      int numberOfIntervals, int idBase, int interval, DateTime end) async {
    final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
        FlutterLocalNotificationsPlugin();
    for (int i = 0; i < numberOfIntervals; i++) {
      final scheduledTime = start.add(Duration(milliseconds: i * interval));
      if (scheduledTime.isBefore(end)) {
        final tzScheduledTime = _convertToTZDateTime(scheduledTime);
        // Schedule your notification here
        await flutterLocalNotificationsPlugin.zonedSchedule(
          idBase + i,
          'Notification Title',
          'Notification Body',
          tzScheduledTime,
          const NotificationDetails(
            android: AndroidNotificationDetails(
              'channel id',
              'channel name',
            ),
          ),
          androidAllowWhileIdle: true,
          uiLocalNotificationDateInterpretation:
              UILocalNotificationDateInterpretation.wallClockTime,
          matchDateTimeComponents:
              DateTimeComponents.time, // To match the exact time for recurrence
        );
      }
    }
  }```
