Flutter BottomNavigationBar center icon style

Question

Is there a way to add a notch above the center icon in BottomNavigationBar? Something like in this image:

I currently have something like this generating the navigation:

        return BottomNavigationBar(
          type: BottomNavigationBarType.fixed,
          fixedColor: Color(0xff2398C3),
          showSelectedLabels: false,
          showUnselectedLabels: false,
          currentIndex: snapshot.data.index,
          onTap: _bottomNavBarBloc.pickItem,
          items: [
            BottomNavigationBarItem(
              title: Text('Search'),
              icon: Icon(Icons.search),
            ),
            BottomNavigationBarItem(
              title: Text('Browse'),
              icon: Icon(Icons.view_list),
            ),
            BottomNavigationBarItem(
              title: Text('Icon'),
              icon: Container(
                child: FlutterLogo(
                  size: 35.0,
                ),
              ),
            ),
            BottomNavigationBarItem(
              title: Text('Favorites'),
              icon: Icon(Icons.bookmark),
            ),
            BottomNavigationBarItem(
              title: Text('Settings'),
              icon: Icon(Icons.settings),
            ),
          ],
        );
