What happened?

Hi, I simulated the code

The code is in the example folder at this address： https://github.com/jb3rndt/PersistentBottomNavBarV2

you need to replace the main.dart code in your example with the following code to reproduce the bug.

Thanks.

Steps to reproduce

Refer to the video, thank you

This is a dup of #149, and I provided a workaround in there.

You configured handleAndroidBackButtonPress: false, which prevents the package from handling back button presses. In combination with the pushReplacementNamed at the top, this indeed causes the app to minimize as intended.
