我不确定这是否是最干净的解决方案，但您可以向WebView中注入一些JavaScript来获取一些数据，然后将其传递回来。

handleMessage(message) {
  console.log(message.nativeEvent.data);
}

render() {
  return (
    <WebView
      source={{ uri: "https://wonderloveapp.com" }}
      injectedJavaScript="window.postMessage(document.title)"
      onMessage={this.handleMessage}
    />
  )
}

您可以使用injectJavaScript或injectedJavaScript prop 将Javasctipt代码注入到您加载的URL并获取页面标题。请查看this answer以了解如何使用javascript获取tile。
然后当你获得头衔时，你可以使用onMessage prop 传递到React原生方。

存在包含title属性的NativeEvent。https://github.com/react-native-webview/react-native-webview/blob/master/docs/Reference.md#onloadstart

<WebView
  source={{
    uri: route.params.url,
  }}
  onLoadStart={(event) => {
    navigation.setOptions({
      headerTitle: event.nativeEvent.title, // get webpage title
    });
  }}
></WebView>

下面是如何创建一个浏览器屏幕，在使用webview的同时，使用react钩子将标题和url放在标题中。

import React from "react";
import { useEffect } from "react";
import { useState } from "react";
import { Text } from "react-native";
import { View, SafeAreaView, ActivityIndicator } from "react-native";
import { WebView } from "react-native-webview";
const BroswerScreen = ({ route, navigation }) => {
  const { url } = route.params;
  const [isLoading, setLoading] = useState(true);
  const [title, setTitle] = useState(null)
  const [urlHeader, setUrlHeader] = useState(null)

  useEffect(() => {
    console.log(title)
    console.log(urlHeader)
    console.log(isLoading)
    if(title && urlHeader){
      navigation.setOptions({
        headerStyle: { height: 100 },
        headerTitle: ()=> (
        <View>
          <Text numberOfLines={1} style={{fontSize: 16, fontWeight: "bold"}}>{title}</Text>
          <Text numberOfLines={1}>{urlHeader}</Text>
        </View>)
      });
    }

  }, [title,urlHeader, isLoading]);
  return (
    <SafeAreaView style={{ flex: 1, backgroundColor: "white" }}>
      <WebView
        startInLoadingState={true}
        renderLoading={() => {
          return <Spinner />;
        }}
        style={{ flex: 1 }}
        source={{ uri: url }}
        injectedJavaScript= "window.ReactNativeWebView.postMessage(document.title)"
        onMessage={(message) => setTitle(message.nativeEvent.data)}
        onNavigationStateChange={(event) => {setTitle(event.title); setUrlHeader(event.url); setLoading(false)}}
      />
    </SafeAreaView>
  );
};
const Spinner = () => {
  return (
    <View
      style={{
        flex: 1,
        height: "100%",
        width: "100%",
      }}
    >
      <ActivityIndicator color={"blue"} size="large" />
    </View>
  );
};
export default BroswerScreen;

您可以使用类似于以下内容的方法转到此屏幕

onPress(
      navigation.navigate(BROWSERSCREEN, {
        url: "https://www.mylink.com",
      })
    )
