detectTransformGestures
suspend fun PointerInputScope.detectTransformGestures(
panZoomLock: Boolean = false,
onGesture: (centroid: Offset, pan: Offset, zoom: Float, rotation: Float) -> Unit,
)A gesture detector for rotation, panning, and zoom. Once touch slop has been reached, the user can use rotation, panning and zoom gestures. onGesture will be called when any of the rotation, zoom or pan occurs, passing the rotation angle in degrees, zoom in scale factor and pan as an offset in pixels. Each of these changes is a difference between the previous call and the current gesture. This will consume all position changes after touch slop has been reached. onGesture will also provide centroid of all the pointers that are down.
If panZoomLock is true, rotation is allowed only if touch slop is detected for rotation before pan or zoom motions. If not, pan and zoom gestures will be detected, but rotation gestures will not be. If panZoomLock is false, once touch slop is reached, all three gestures are detected.
