onScaleRotateDown property

dynamic Function(PointerDownEvent, Size)? onScaleRotateDown
final

Callback for handling pointer down events associated with scale and rotate gestures.

This callback is triggered when the user presses down on the widget to begin a scaling or rotating gesture. It provides both the pointer event and the size of the widget being interacted with, allowing for precise manipulation.

  • Parameters:
    • event: The PointerDownEvent containing details about the pointer interaction, such as position and device type.
    • size: The Size of the widget being manipulated, useful for calculating scaling and rotation transformations relative to the widget's dimensions.

Implementation

final Function(PointerDownEvent, Size)? onScaleRotateDown;
