Hi.
A bug has been introduced in a recent version when dragging an appointment in the calendar:
It's a null check exception in the _updateAppointmentDragUpdateCallback() method of the _CustomCalendarScrollViewState class.

The line in question seems to expect a non null value, but the _getDateFromPosition is returning null.
Kind regards,
Cris
