How to get the dropped resource details in the Flutter Calendar (SfCalendar)?
In the Flutter Calendar, you can retrieve dropped resource details by using the onDragEnd callback of the calendar widget.
Step 1: Initialize the calendar and enable the allowDragAndDrop property.
child: SfCalendar( view: CalendarView.timelineWeek, allowedViews: _allowedViews, dataSource: _events, allowDragAndDrop: true, onDragEnd: dragEnd, ),
STEP 2: Use the onDragEnd callback, to access target and source resource details.
void dragEnd(AppointmentDragEndDetails appointmentDragEndDetails) {
var targetResource = appointmentDragEndDetails.targetResource;
var sourceResource = appointmentDragEndDetails.sourceResource;
_showDialog(targetResource!, sourceResource!);
}
void _showDialog(
CalendarResource targetResource, CalendarResource sourceResource) async {
await showDialog(
builder: (context) => AlertDialog(
title: const Text("Dropped resource details"),
contentPadding: const EdgeInsets.all(16.0),
content: Text("You have dropped the appointment from " +
sourceResource.displayName +
" to " +
targetResource.displayName),
actions: <Widget>[
TextButton(
child: const Text('OK'),
onPressed: () {
Navigator.pop(context);
})
],
),
context: context,
);
}
