The position is reset when the scroll position of the listview is cached #18

I'm caching the ListView for page navigation(using a PageStorageKey). So that users won't have to scroll from the top each time. But I noticed the draggable scrollbar is reset when the page is navigated back. So I cannot drag the handler to the top (which is already in the top) when the list view is still in the middle. I think it should keep sync to the list view.

same problem, but works fine with the normal Scrollbar and RawScrollbar Widgets

and in my case only a problem in the datasearch objekt with Listview.builder and "itemBuilder: (context, index) => ListTile(...", it works fine on other positions in my app with Listview(...

workaround could be: putting a normal Listview over the Listview.builder can someone confirm or test, too? thx
