getSchedule method
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]) {
var cronIterator = Cron().parse(
configuration!.cronExpression,
Settings().timezone,
tz.TZDateTime.from(from, tz.getLocation(Settings().timezone)));
final List<DateTime> schedule = [];
int count = 0;
while (cronIterator.next().isBefore(to) && count < max) {
schedule.add(cronIterator.current());
count++;
}
return schedule;
}
