SliverTree<T extends Object> class

A wrapper around SliverList that adds basic tree viewing capabilities.

Usage:

@override
Widget build(BuildContext context) {
  return CustomScrollView(
    slivers: [
      SliverTree<Node>(
        controller: treeController,
        nodeBuilder: (BuildContext context, TreeEntry<Node> entry) {
          ...
        },
      ),
    ],
  );
}
