DragSelectionUpdateCallback typedef

void DragSelectionUpdateCallback (DragStartDetails startDetails, DragUpdateDetails updateDetails)

Signature for when a pointer that's dragging to select text has moved again.

The first argument startDetails contains the details of the event that initiated the dragging.

The second argument updateDetails contains the details of the current pointer movement. It's the same as the one passed to DragGestureRecognizer.onUpdate.

This signature is different from GestureDragUpdateCallback to make it easier for various text fields to use TextSelectionGestureDetector without having to store the start position.

Implementation

typedef DragSelectionUpdateCallback = void Function(DragStartDetails startDetails, DragUpdateDetails updateDetails);
