Use case

Due to the change made by #114439 for BottomAppBar my app designs are broken you can see below:

Material 2	Material 3

GitHub gist to reproduce the effect and DartPad link.

Flutter 3.5.0-12.0.pre.142 • channel master • https://github.com/flutter/flutter.git
Framework • revision c551fe3de1 (29 minutes ago) • 2022-11-07 01:32:24 -0500
Engine • revision 4e45cfb4a2
Tools • Dart 2.19.0 (build 2.19.0-374.0.dev) • DevTools 2.19.0

Proposal

Currently, in bottom_app_bar.dart flutter is setting padding to the child like this when material 3 is active:

So, I think one solution for this is to provide an option to modify this padding set by material3 through BottomAppBar properties.
