How to pop with withNavBar true?

[y0unghe]

I tried to push withNavBar:false.

pushNewScreen(context, withNavBar: false, screen: LoginPage());

But when I pop: Navigator.of(context).pop(); The nav bar won't appear. So how should I pop withNavBar:true?

Hi, is there any solution for this case? I have the same case like @y0unghe's

[zalviandyr]

I solve this problem by creating a double context. PersistentBottomNavBar Context and Navigator Context.
Create a singleton class named App, that have 2 properti

class App {
  static GlobalKey<NavigatorState> navigator = GlobalKey();
  static BuildContext context = navigator.currentContext!;
}

So the App class has a navigator key which has a context and assigned in MaterialApp in main.dart. And dont forget to reassigned App.context in PersistentTabView.selectedTabScreenContext() method to update the context of the current page.

MaterialApp(navigatorKey: App.navigator),

PersistentTabView(
      selectedTabScreenContext: (context) {
        if (context != null) {
          App.context = context;
        }
      },
)

And then we if pop from withNav: false send context in current widget Navigator.pop(context) and withNav: true send App.context Navigator.pop(App.context).

Hope this help.
