如何使用react导航在堆栈/选项卡导航器之间实现共享搜索栏输入？

import React, { createContext, useState } from 'react';

export const SearchContext = createContext();

export const SearchProvider = ({ children }) => {
  const [searchText, setSearchText] = useState('');

  const updateSearchText = (text) => {
    setSearchText(text);
  };

  return (
    <SearchContext.Provider value={{ searchText, updateSearchText }}>
      {children}
    </SearchContext.Provider>
  );
};

import React from 'react';
import { SearchProvider } from './SearchContext';
import AppNavigator from './AppNavigator';

const App = () => {
  return (
    <SearchProvider>
      <AppNavigator />
    </SearchProvider>
  );
};

export default App;

import React, { useContext } from 'react';
import { View, TextInput, Button } from 'react-native';
import { SearchContext } from './SearchContext';

const Screen1 = () => {
  const { searchText, updateSearchText } = useContext(SearchContext);

  return (
    <View>
      <TextInput
        value={searchText}
        onChangeText={updateSearchText}
        placeholder="Search..."
      />
      <Button title="Search" onPress={() => console.log(searchText)} />
    </View>
  );
};

export default Screen1;

import React, { useContext } from 'react';
import { View, Text } from 'react-native';
import { SearchContext } from './SearchContext';

const Screen2 = () => {
  const { searchText } = useContext(SearchContext);

  return (
    <View>
      <Text>Search Text: {searchText}</Text>
    </View>
  );
};

export default Screen2;
