localToGlobal method
Convert a point from the viewfinder's coordinate system to the global 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 globalToLocal.
Implementation
Vector2 localToGlobal(Vector2 point, {Vector2? output}) {
return transform.localToGlobal(point, output: output);
}
