Attach to the bottom of Scaffold instead of the bottom of the screen

[wiradikusuma]

My app has a bottom padding for ads:

Padding(
	child: _inside(ctx),
	padding: EdgeInsets.only(bottom: 100), // For ads
)


Widget _inside(ctx) => Scaffold(
	appBar: ...,
        body: ...,
        floatingActionButton: ...,
);

Unfortunately, the ad widget hides the flushbar, presumably because it is native. How do I make the flushbar appear from the bottom of Scaffold instead of the bottom of the screen? It doesn't make sense anyway to overlay on ads.
