[Flutter] Create an app with static app bar and a back button on the top left

I am new to flutter and I am trying to create a simple app with a "static" that doesn't change between pages. I want also that the app bar will have a back button the page is changed, how can i keep truck of that.

I have a created a widget for the app bar and tried making it statefull widget and save the Navigator state so that when it updates i will update my appBar widget.

I will add the code for how i change pages as well:

onTap: () {
Navigator.push(
context,
PageRouteBuilder(
pageBuilder: (context, animation, secondaryAnimation) =>
UserInfoPage(data: 'Hello from Home Page!'),
transitionsBuilder:
(context, animation, secondaryAnimation, child) {
return FadeTransition(opacity: animation, child: child);
},
),
);
},
