buildAroundTransformAndScrollbar method
Gets called every time the transform changes. Can be used to a widget over the scrollbars and the transformed widget, e.g. a indicator for the zoom.
Instead of overriding buildTransformAndScrollbars, consider overriding this method.
The default implementation just returns the child.
Implementation
Widget buildAroundTransformAndScrollbar(BuildContext context, Widget child) {
return child;
}
