    NavigationDrawer required parameter children, add this parameter like below

          drawer: const NavigationDrawer(
        children: [],
      ),

    For drawer you have provide required children parameter

     drawer: const NavigationDrawer(
            children: <Widget>[
             //widgets here
             
            ],
          ),

    you can also accomplish drawer by using Drawer widget
    I have used ListView as child of Drawer

    drawer: Drawer(
        backgroundColor: kPrimaryBackGroundColor,
        child: ListView(
          children: [
            NavHeader(),
            const Divider(
              color: kPrimaryBorderColor,
            ),
            DrawerItem("About Us", Icons.local_offer_outlined ,  AboutUs()),
            DrawerItem("Account", Icons.account_circle, ProfileScreen()),
            DrawerItem("Stats", Icons.query_stats, UserStats())

          ],
        ),
      )

    ,
