periodicallyShow method Null safety

  1. @override
Future<void> periodicallyShow(
  1. int id,
  2. String? title,
  3. String? body,
  4. RepeatInterval repeatInterval,
  5. {AndroidNotificationDetails? notificationDetails,
  6. String? payload,
  7. bool androidAllowWhileIdle = false}

Periodically show a notification using the specified interval. For example, specifying a hourly interval means the first time the notification will be an hour after the method has been called and then every hour after that.
