getSchedule method

  1. @override
List<DateTime> getSchedule(
  1. DateTime from,
  2. DateTime to, [
  3. int max = 100
])
override

An ordered list of timestamp generated by this trigger for a given period. This is mainly used for persistently scheduling a list of AppTasks from triggers that implement the Schedulable interface.

Implementation

@override
List<DateTime> getSchedule(DateTime from, DateTime to, [int max = 100]) {
  List<DateTime> schedule = [];
  DateTime timestamp = configuration!.firstOccurrence;
  int count = 0;

  while (timestamp.isBefore(to) && count < max) {
    if (timestamp.isAfter(from)) schedule.add(timestamp);
    timestamp = timestamp.add(configuration!.period);
    count++;
  }

  return schedule;
}
