BottomAppBar Floating action button notch/inset is not transparent

Question

I\'ve added a BottomAppBar to scaffold in a materialApp, and to that I\'ve added a fab with a inset at the center. The code looks somewhat like this

Answer 1

You just need to be on the flutter channel: master and then add to Scaffold:

Scaffold(
   extendBody: true
);

and it should be transparent :)
