buildTransformAndScrollbars method

@override Widget buildTransformAndScrollbars(BuildContext context, Widget child)

Gets called every time the transform changes. The default implementation returns a ListenableBuilder that listens to the rebuildNotifier and rebuilds the scrollbars and the transform, but not the child.

Instead of overriding this method, consider overriding buildAroundTransformAndScrollbar.

Implementation

@override
Widget buildTransformAndScrollbars(BuildContext context, Widget child) {
  return ListenableBuilder(
    listenable: rebuildNotifier,
    builder: (context, c) {
      return buildAroundTransformAndScrollbar(
        context,
        TransformAndScrollbarsWidget(
          scrollbarController: scrollbarController,
          transform: transformForRender,
          onResize: () => Future.microtask(afterResize),
          overrideSize: overrideSize,
          child: child,
        ),
      );
    },
  );
}
