getNextDate method
Gets the next valid date for a notification schedule. The schedule
parameter is a valid NotificationSchedule model that specifies the
notification schedule. The optional fixedDate parameter is a DateTime
value that represents the reference date to simulate a schedule in a
different time. If this parameter is omitted, the reference date will be
set to the current date and time.
This method returns a Future that resolves to a DateTime value that
represents the next valid date for the notification schedule. If the
notification schedule has expired or is invalid, the method will return
null. If the notification schedule is a one-time event, the method will
return the event's date and time. If the notification schedule is a
repeating event, the method will return the next valid date and time for
the event.
Implementation
@override
Future<DateTime?> getNextDate(NotificationSchedule schedule,
{DateTime? fixedDate}) async {
return null;
}
