globalToLocal method
Convert a point from the global coordinate system to the viewfinder's coordinate system.
Use output
to send in a Vector2 object that will be used to avoid
creating a new Vector2 object in this method.
Opposite of localToGlobal.
Implementation
Vector2 globalToLocal(Vector2 point, {Vector2? output}) {
return transform.globalToLocal(point, output: output);
}
