PersistentBottomNavBarItem(
        onPressed: _openRatingsLayer,

        icon: Icon(
          Icons.add,
          color: Colors.white,
          size: 35,
        ),
        title: ("Add"),
        activeColorPrimary: Colors.orange.shade800,
        inactiveColorPrimary: Colors.grey,
      ),

void _openRatingsLayer() {
    showModalBottomSheet(
      elevation: 0,
      backgroundColor: Colors.white,
      isDismissible: true,
      isScrollControlled: true,
      context: context,
      builder: (ctx) {
        return Padding(
          padding:
              EdgeInsets.only(bottom: MediaQuery.of(ctx).viewInsets.bottom),
          child: const DummyScreen(),
        );
      },
    );
  }

I’m expecting that when i click on the add navbar item, it shows me modalbottomsheet and not take me to a new screen… that’s why i tried to use the onPressed function of the persistentNavBarItem but it gave an error
