Is there any method to make a tree view with sticky headers? #98
Description
I want a tree view in which the parent header of contents is a sticky header.
I have made implementation similar to example/lib/examples/nested.dart.
But the issue with MultiSliver is that it is not good for large list.
There are other packages which implement tree view in an optimised way - animated_tree_view, flutter_fancy_tree_view, they have sliver implementations but I can't find a way to use them with sticky header.
Is it possible to implement a tree view with sticky headers?
