onDragCancel property

VoidCallback? onDragCancel
final

Called when a drag operation is cancelled.

This is called instead of onDragEnd when:

  • The gesture recognizer cancels the gesture
  • The widget is disposed mid-drag
  • The pointer up handler detects the original pointer released

If null, onDragEnd is called with empty DragEndDetails as a fallback.

Implementation

final VoidCallback? onDragCancel;
