React本地路由器流量-如何在android中从导航栏(而不是硬件后退按钮)访问back？

import React from 'react';
import { Button } from 'react-native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function HomeScreen({ navigation }) {
  return (
    <Button
      title="Go to Details"
      onPress={() => navigation.navigate('Details')}
    />
  );
}

function DetailsScreen({ navigation }) {
  return (
    <>
      <Button
        title="Go back"
        onPress={() => navigation.goBack()}
      />
    </>
  );
}

export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="Home">
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Details" component={DetailsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}
