getEventsOnDay method

List<CalendarEventData<T>> getEventsOnDay(DateTime date)

Returns events on given day.

To overwrite default behaviour of this function, provide eventFilter argument in EventController constructor.

Implementation

List<CalendarEventData<T>> getEventsOnDay(DateTime date) {
  if (eventFilter != null) return eventFilter!.call(date, this.events);

  final events = <CalendarEventData<T>>[];

  for (var i = 0; i < _events.length; i++) {
    if (_events[i].year == date.year) {
      final monthEvents = _events[i]._months;

      for (var j = 0; j < monthEvents.length; j++) {
        if (monthEvents[j].month == date.month) {
          final calendarEvents = monthEvents[j]._events;

          for (var k = 0; k < calendarEvents.length; k++) {
            if (calendarEvents[k].date.day == date.day)
              events.add(calendarEvents[k]);
          }
        }
      }
    }
  }

  final daysFromRange = <DateTime>[];
  for (final rangingEvent in _rangingEventList) {
    for (var i = 0;
        i <= rangingEvent.endDate.difference(rangingEvent.date).inDays;
        i++) {
      daysFromRange.add(rangingEvent.date.add(Duration(days: i)));
    }
    if (rangingEvent.date.isBefore(rangingEvent.endDate)) {
      for (final eventDay in daysFromRange) {
        if (eventDay.year == date.year &&
            eventDay.month == date.month &&
            eventDay.day == date.day) {
          events.add(rangingEvent);
        }
      }
    }
  }

  return events;
