如何在app (不是geo)中保存用户的最后一个位置？React Native

import React, { useEffect } from 'react';
import { View, Text, Button } from 'react-native';
import AsyncStorage from '@react-native-async-storage/async-storage';
import Geolocation from '@react-native-community/geolocation';

const App = () => {
  useEffect(() => {
    // 获取用户位置信息
    Geolocation.getCurrentPosition(
      position => {
        const { latitude, longitude } = position.coords;
        // 存储用户位置信息
        AsyncStorage.setItem('lastLocation', JSON.stringify({ latitude, longitude }));
      },
      error => console.log(error),
      { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }
    );
  }, []);

  const getLastLocation = async () => {
    // 获取存储的最后一个位置信息
    const lastLocation = await AsyncStorage.getItem('lastLocation');
    if (lastLocation) {
      const { latitude, longitude } = JSON.parse(lastLocation);
      console.log('Last Location:', latitude, longitude);
    }
  };

  return (
    <View>
      <Text>Save User's Last Location</Text>
      <Button title="Get Last Location" onPress={getLastLocation} />
    </View>
  );
};

export default App;
