createMaterialBottomTabNavigator Cant将barstyle设置为透明

Question

由于某种原因，我的主动色无法正常工作。相反，它的默认白色/黑色处于活动状态或非活动状态。另外，我想以某种方式将背景barstyle颜色设置为透明。你有什么想法吗？

export default createMaterialBottomTabNavigator(
     {
    Home: HomeStack,
    Settings: SettingsStack,
    Menu:Doctors,
    super:Page1,
    props:Page2
    },
     {
        navigationOptions: ({ navigation }) => ({
      tabBarIcon: ({ focused, tintColor }) => {
        const { routeName } = navigation.state;
        let iconName;
        if (routeName === 'Home') {
          iconName = 'home'
        } else if (routeName === 'Settings') {
          iconName = 'settings'
        } else if (routeName === 'Menu'){
          iconName = 'description'
        }else if (routeName === 'super'){
          iconName = 'menu'
        }else if (routeName === 'props'){
          iconName = 'notifications'
        }


        return <Icon name={iconName} size={23} color={tintColor} />;

      },
        }),
        tabBarPosition: 'bottom',
        tabBarOptions: {
          activeTintColor: 'tomato',
          inactiveTintColor: 'gray',
        },
        animationEnabled: true,
        swipeEnabled: false,
        shifting :true
      }
      );
