navigate to lib/views/after_auth_screens/events/event_calendar.dart

modify _getCalendarDataSource method as shown below.

_AppointmentDataSource _getCalendarDataSource(List<Event> eventsList) {
  final appointments = <Appointment>[];
  final colors = [
    Colors.green,
    Colors.blue,
    Colors.red,
    Colors.orange,
    Colors.purple,
    Colors.pink,
  ];
  int index = 0;
  // looping through all the events created in the organization.
  eventsList.forEach((event) {
    DateTime? startDate;
    DateTime? endDate;

    /// change made here, code related to the fix.
    if (event.startDate!.contains('/')) {
      startDate = DateFormat('MM/dd/yyyy').parse(event.startDate!);
    } else {
      startDate = DateFormat('yyyy-MM-dd').parse(event.startDate!);
    }

    /// change made here, code related to the fix.
    if (event.endDate!.contains('/')) {
      endDate = DateFormat('MM/dd/yyyy').parse(event.endDate!);
    } else {
      endDate = DateFormat('yyyy-MM-dd').parse(event.endDate!);
    }

    print("${event.startTime!}##############################");
    final startTime = parseTime(event.startTime ?? '14:23:01');
    final endTime = parseTime(event.endTime ?? '21:23:01');

    // adding appointments on the calender for event[index] date time.
    appointments.add(
      Appointment(
        startTime: startDate
            .add(Duration(hours: startTime.hour, minutes: startTime.minute)),
        endTime:
            endDate.add(Duration(hours: endTime.hour, minutes: endTime.minute)),
        subject: event.title!,
        color: colors[index % colors.length],
        location: event.location,
        id: event.id,
      ),
    );
    index++;
  });

  return _AppointmentDataSource(appointments);
}

Cause: We are getting 2 different formats of Date from eventList.

1. YYYY-MM-DD
2. YYYY/MM/DD

so the parseTime method is facing issue while parsing these fomats. I have added 2 if else blocks to handle these two types of formats.
