android – Flutter – Persistant navigation bar not working correctly

I’m utilizing persistant navigation bar in flutter however it’s showing on some pages & not showing on the identical pages.

really i used to be dealing with a difficulty that when from different buttons i need to change the energetic tab. so i merged the drawer into the house web page the place I had persistant bar code. however i’ve mounted that challenge

however the brand new challenge occurred. i had a challenge that the right way to change the appbar title i mounted that too utilizing getx. I’m altering the appbar title in init state of that web page.

however then after that the navigation bar began disappearing I do not perceive the right way to repair that challenge and why is that this being occurred…
