Calendar drag drop error

Hello.


I'm excited about starting to use the new drag drop support added to the calendar.

However I'm getting stuck pretty much at the beginning. I'm getting the error below.

I'm using my own Appointment class because I need the additional details such as the color that should be displayed for it, etc.

When I set  allowDragDrop to true it seems that the calendar is expecting an instance of the appointment class defined in the calendar package.

Can you suggest a way forward?


Error:


The following TypeErrorImpl was thrown while handling a gesture:

Expected a value of type 'Appointment' (in package:edent/modules/calendar/model/appointment.dart),

package:edent/…/model/appointment.dart:1

but got one of type 'Appointment' (in

package:syncfusion_flutter_calendar/src/calendar/appointment_engine/appointment.dart)

package:syncfusion_flutter_calendar/…/appointment_engine/appointment.dart:1

When the exception was thrown, this was the stack:
