Scaffold(
      key: _key,
      drawerEnableOpenDragGesture: true,
      body: Builder(
        builder: (context) {
          return PersistentTabView(
            navBarHeight: 60,
            decoration: NavBarDecoration(
              boxShadow: [
                BoxShadow(
                  color: Colors.black.withOpacity(0.2), // Shadow color
                  offset: const Offset(0, -3), // Changes position of shadow
                  blurRadius: 6, // Changes size of shadow
                  spreadRadius: 2, // Changes intensity of shadow
                ),
              ],
            ),
            backgroundColor: Colors.white,
            context,
            screens: screens(),
            items: navBarItems(),
            controller: controller,
            navBarStyle: NavBarStyle.style9,
            popAllScreensOnTapOfSelectedTab: true,
            stateManagement: false,
           
          );
        }
      ),
    );

I was trying to make a rebuild on every switching but it is not working it stays at the same state at which it was left. I also tried making statemanagent to false, but it remains the same..
