Change background of scaffold within inner drawer

[joshbenaron]

Hey,
I perform a slide transition on the scaffold. How do I change the background colour below the scaffold? It looks like an internal feature of inner drawer? I guess it's because the scaffold has a lower opacity (I think). Is there a way of customising this opacity?

colorTransitionChild: Colors.black54
colorTransitionScaffold: Colors.black54

for background colour below the scaffold:

scaffold: Container(
    color: Colors.black54,
    child: Scaffold( ..)
 )
