Description

When you execute dart dev/tools/gen_defaults/bin/gen_defaults.dart on the master branch, It should not make any changes to packages/flutter unless a new template is added for a PR.

However, I see this bottom_app_bar.dart is out of sync with gen_defaults/lib/bottom_app_bar.dart on master after #106525.
(I also noticed this with other recently landed classes but they seemed to be fixed now).

Steps to reproduce

1. git clone [email protected]:flutter/flutter.git

2. cd flutter and dart dev/tools/gen_defaults/bin/gen_defaults.dart

Result

The shape is out of sync.
