如何在TabNav中添加处理DrawerNav显示的按钮

// App.js

import React from 'react';
import { createAppContainer } from 'react-navigation';
import { createBottomTabNavigator } from 'react-navigation-tabs';
import { createDrawerNavigator } from 'react-navigation-drawer';

import HomeScreen from './screens/HomeScreen';
import ProfileScreen from './screens/ProfileScreen';
import DrawerScreen from './screens/DrawerScreen';

const TabNavigator = createBottomTabNavigator({
  Home: HomeScreen,
  Profile: ProfileScreen,
}, {
  tabBarOptions: {
    // 自定义Tab样式
  },
  navigationOptions: {
    // 自定义Tab标题
  },
});

const DrawerNavigator = createDrawerNavigator({
  Tabs: TabNavigator,
  Drawer: DrawerScreen,
});

const AppContainer = createAppContainer(DrawerNavigator);

export default function App() {
  return <AppContainer />;
}

// DrawerScreen.js

import React from 'react';
import { View, Text, Button } from 'react-native';

export default function DrawerScreen({ navigation }) {
  return (
    <View>
      <Text>Drawer Screen</Text>
      <Button
        title="Toggle Drawer"
        onPress={() => navigation.toggleDrawer()}
      />
    </View>
  );
}
