AllDay and date start / end bug

[ak1987]

Describe the bug Error 400 on creating allday event (iOS): To create or update an all day event you must provide calendar ID, event with a title and event's start date

Working: var test = await _deviceCalendarPlugin.createOrUpdateEvent(Event(calendarId, title: 'Title 1', allDay: true, start: TZDateTime.local(2024, 6, 20), end: TZDateTime.local(2024, 6, 20)));

Not working: var test = await _deviceCalendarPlugin.createOrUpdateEvent(Event(calendarId, title: 'Title 1', allDay: true, start: TZDateTime.local(2024, 6, 20)));

device_calendar.dart, lines ~236:

_assertParameter(
          result,
          !(event.allDay == true && (event.calendarId?.isEmpty ?? true) ||
              event.start == null ||
              event.end == null),
          ErrorCodes.invalidArguments,
          ErrorMessages.createOrUpdateEventInvalidArgumentsMessageAllDay,
        );

Expected behavior All day event creates without date end parameter
