Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Use case

StatefulNavigationShell is a widget that is built in StatefulShellRoute. It has a goBranch method on the widget itself

https://pub.dev/documentation/go_router/latest/go_router/StatefulNavigationShell/goBranch.html

This is unsafe as a widget class can be reused multiple time in a screen. Although it is not an issue now, it can be a foot gun if someone refactor it in the future without knowing this method exists.

Proposal

We should find a new way to expose this API.
