How do I properly add a drawer to this example while keeping the tab specific app bar? When I add one to the Scaffold on one of the pages it works, but the Drawer is not the full vertical size of the screen (only top of the nav bar and up).
But when I add it to the Scaffold of the ScaffoldWithNavBar widget it doesn't show up at all unless I also add an AppBar, which will then conflict with the page specific AppBar...
Is it possible to get the Drawer on one of the branches to become the full vertical screen?
