scheduleNotification method

@override Future<int> scheduleNotification({ int? id, required String title, String? body, required DateTime schedule, })

Schedule a notification with id, title, and body at the schedule time. If the id is not specified, a random id will be generated.

Returns the id of the notification created.

Implementation

@override
Future<int> scheduleNotification({
  int? id,
  required String title,
  String? body,
  required DateTime schedule,
}) async {
  tz.initializeTimeZones(); // for some strange reason, the time zones are not always initialized when this method is called, so we initialize them here to be sure

  id ??= _random.nextInt(1000);
  final time = tz.TZDateTime.from(
    schedule,
    tz.getLocation(Settings().timezone),
  );

  await FlutterLocalNotificationsPlugin().zonedSchedule(
    id: id,
    title: title,
    body: body,
    scheduledDate: time,
    notificationDetails: _platformChannelSpecifics,
    androidScheduleMode: AndroidScheduleMode.exactAllowWhileIdle,
  );

  return id;
}
