Code to reproduce the problem

class BottomNavigation extends StatefulWidget {
  const BottomNavigation({Key? key}) : super(key: key);

  @override
  State<BottomNavigation> createState() => _BottomNavigationState();
}

class _BottomNavigationState extends State<BottomNavigation> {
  // @override
  // void initState() {
  //   if (API.isLoggenIn == null || API.isLoggenIn == false) {
  //     Navigator.pushReplacement(
  //         context, MaterialPageRoute(builder: (context) => GymLoginPage()));
  //   }
  //   super.initState();
  // }

  PersistentTabController _controller = PersistentTabController(
    initialIndex: 0,
  );
  @override
  Widget build(BuildContext context) {
    final screens = [GymHome(), MembershipScreen(), CategoryScreen(), AnnouncementScreen(), ProfileScreen()];
    List<PersistentTabConfig> tabs() => [
          PersistentTabConfig(
            screen: const GymHome(),
            item: ItemConfig(
              activeForegroundColor: bottomNavigationActiveIconColor,
              inactiveForegroundColor: bottomNavigationInActiveIconColor,
              icon: Icon(CupertinoIcons.home),
              //title: "Home",
            ),
          ),
          PersistentTabConfig(
            screen: const MembershipScreen(),
            item: ItemConfig(
              activeForegroundColor: bottomNavigationActiveIconColor,
              inactiveForegroundColor: bottomNavigationInActiveIconColor,
              icon: Icon(CupertinoIcons.creditcard),
              //title: "Wishlist",
            ),
          ),
          PersistentTabConfig(
            screen: CategoryScreen(),
            item: ItemConfig(
              icon: Icon(CupertinoIcons.bag),
              activeForegroundColor: bottomNavigationActiveIconColor,
              inactiveForegroundColor: bottomNavigationInActiveIconColor,
              //title: "Categories",
            ),
          ),
          PersistentTabConfig(
            screen: const AnnouncementScreen(),
            item: ItemConfig(
              icon: Icon(CupertinoIcons.bell),
              activeForegroundColor: bottomNavigationActiveIconColor,
              inactiveForegroundColor: bottomNavigationInActiveIconColor,
              //title: "Cart",
            ),
          ),
          PersistentTabConfig(
            screen: const ProfileScreen(),
            item: ItemConfig(
              icon: const Icon(Icons.person),
              activeForegroundColor: bottomNavigationActiveIconColor,
              inactiveForegroundColor: bottomNavigationInActiveIconColor,
              //title: "Account",
            ),
          ),
        ];
    return Scaffold(
        bottomNavigationBar: PersistentTabView(
      navBarOverlap: NavBarOverlap.full(),
      controller: _controller,
      tabs: tabs(),
      navBarBuilder: (navBarConfig) => Style4BottomNavBar(
        navBarConfig: navBarConfig,
        navBarDecoration: NavBarDecoration(
          //boxShadow: const [BoxShadow(color: Colors.grey, blurRadius: 5)],
          color: bottombackgroundColor,
        ),
      ),
      backgroundColor: bottombackgroundColor,
      stateManagement: true,
      popAllScreensOnTapAnyTabs: true,
      popActionScreens: PopActionScreensType.all,
      screenTransitionAnimation: const ScreenTransitionAnimation(
        curve: Curves.ease,
        duration: Duration(milliseconds: 200),
      ),
    ));
  }
in the above code there is a profile page and there i tried to call ScaffoldMessenger.of(context).showSnackBar(SnackBar(
                                              content: Text("Referral Code Copied"),
                                            )); 
at that time issue occured

The problem is that the PersistentTabView is set as the child of the Scaffold.bottomNavigationBar. Instead, just remove the scaffold. The PersistentTabView serves as a container for all the full size screens and the bottom navigation bar.
