How do I use PanelBuilder for multiple lists?

[pengboboer]

I found a solution and it works fine.

I see that the ScrollController in the source code is created like this：

    // prevent the panel content from being scrolled only if the widget is
    // draggable and panel scrolling is enabled
    _sc = new ScrollController();
    _sc.addListener(() {
      if (widget.isDraggable && !_scrollingEnabled) _sc.jumpTo(0);
    });

Then we can extend the PanelController of sliding_up_panel to have the ability to set ScrollController.
Add a setScrollController method to PanelController:

 void setScrollController(ScrollController sc) {
   _panelState!.sc = sc;
 }

Then change the ScrollController of the Panel when jumping to another page and returning to the page，like this:

double offset = listController?.offset ?? 0;
panelController.setScrollController(listScrollController);

Navigator.push(...).then((value) {
  panelController.setScrollController(detailScrollController);
  listController?.jumpTo(offset);
});

This is my demo, if you need it, I hope it can help you.
