从react导航中动态删除drawerItem

import { createDrawerNavigator } from '@react-navigation/drawer';

      </Drawer.Navigator>
    </NavigationContainer>
  );
}

import { DrawerContentScrollView, DrawerItemList, DrawerItem } from '@react-navigation/drawer';

function CustomDrawerContent(props) {
  const { state, navigation } = props;

  // 从state中获取drawerItems
  const drawerItems = state.routes.map((route, index) => ({
    name: route.name,
    key: route.key,
    // 可以根据需要添加其他属性
  }));

  // 删除指定的drawerItem
  const deleteDrawerItem = (itemKey) => {
    // 过滤掉指定的drawerItem
    const updatedDrawerItems = drawerItems.filter(item => item.key !== itemKey);
    // 更新抽屉导航器的routes
    navigation.setParams({ drawerItems: updatedDrawerItems });

          label={item.name}
          onPress={() => navigation.navigate(item.name)}
