Sfcalendar - problem on calendarview.day and calendarview.week

Bug description

When i create an event on 2 days startTime is for example new DateTime(2024,11,1,10,0) endTime is new DateTime(2024,11,4,17,0). It's displayed as it's an all day event. I want to split this in order to see this event on the day column with the exact hour.

Steps to reproduce

Add apointments on 3 days All appointments will be displayed as an allday event

Code sample

appointment.add(_Meeting( _subjectCollection[random.nextInt(7)], startDate, startDate.add(Duration(days: random.nextInt(3))), _colorCollection[random.nextInt(9)], false, ) ```dart [Add your code here] ```

Hi @manuecal,

Currently, we do not have direct support for your requirement. However, we have prepared a workaround solution to handle multi-day events and display them as separate appointments with specific start and end times instead of as all-day events by modifying the appointment data creation logics. We have created a multi-day event from October 21 to October 24, 2024, where a loop iterates through each day, generating individual appointments. On the first day (October 21), the appointment starts at 10:00 AM, while on the last day (October 24), it ends at 5:00 PM. For the intervening days (October 22 and 23), the appointments are set to run from midnight (00:00 AM) to 11:59 PM, effectively treating them as full-day events while maintaining the desired time structure for the overall multi-day appointment. We have shared a code snippet and a sample for your reference. You can modify the sample based on your needs.

Code snippet:

@override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: SfCalendar(
          view: CalendarView.month,
          allowedViews: const [
            CalendarView.day,
            CalendarView.week,
          ],
          dataSource: _getCalendarDataSource(),
        ),
      ),
    );
  }

  _AppointmentDataSource _getCalendarDataSource() {
    List<Appointment> appointments = <Appointment>[];

    DateTime startTime = DateTime(2024, 10, 21, 10, 0);
    DateTime endTime = DateTime(2024, 10, 24, 17, 0);

    // Add appointments for each day
    for (int i = 0; i < 4; i++) {
      DateTime appointmentDate = startTime.add(Duration(days: i));

      // For the first day, set the start time to the original start time
      DateTime currentStartTime = (i == 0)
          ? startTime
          : DateTime(appointmentDate.year, appointmentDate.month,
              appointmentDate.day, 0, 0);

      // For the last day, set the end time to the original end time
      DateTime currentEndTime = (i == 3)
          ? endTime
          : DateTime(appointmentDate.year, appointmentDate.month,
              appointmentDate.day, 23, 59);

      appointments.add(Appointment(
        startTime: currentStartTime,
        endTime: currentEndTime,
        subject: 'Multi-Day Event',
        color: Colors.blue,
        startTimeZone: '',
        endTimeZone: '',
      ));
    }

    return _AppointmentDataSource(appointments);
  }
}

class _AppointmentDataSource extends CalendarDataSource {
  _AppointmentDataSource(List<Appointment> source) {
    appointments = source;
  }
}
