On macos, the scaling gesture uses 2 fingers without pressing on the pad.
The current code effectively requires a finger press in order to start tracking finger motion.
This is fine for dragging but not scaling.
Due to the limitation of Flutter (Listener component), the scaling detects function will not work correctly with the touchpad device.
I cannot do anything about this. Hope you will find a solution soon.
