transformationController property
This controller will be used by the InteractiveViewer in FlutterPainter to notify children widgets of transformation changes.

DO NOT ASSIGN this controller to any widget,
it is automatically used inside the InteractiveViewer in FlutterPainter controller by
this.
However, you can use it to grab information about the transformations.
