PointerCallback typedef

PointerCallback = void Function(double normalizedX, double normalizedY)

Function signature for callbacks that report normalized pointer position.

The normalizedX and normalizedY parameters represent the pointer position normalized to a range of -1.0 to 1.0, where (0,0) is the center of the tracking area.

Implementation

typedef PointerCallback = void Function(double normalizedX, double normalizedY);
