Screen dependent rotation angle

[pavelbabenko]

Hi, I'm trying to create grid with cells. Each cell can be moved and scaled. Cells scaling should work in vertical and horizontals directions and I faced with some issues. To just move cell I obviously use PanGestureHandler, for scaling - PinchGestureHandler. Now I'm facing the issue that I can't scale item by X or Y independently. I thought of using RotateGestureHandler to get angle of my fingers and calculate scaleX, scaleY depending on it, but I can find only delta of rotation.

Can someone help me, how can I get the angle between my fingers in relation of screen?

The alternative way is to get coordinates of 1st and 2nd pointers separately. I tried to use 2 PanGestureHandlers, but no success
