Firestore在React Native中显示查询结果

import React, { useEffect, useState } from 'react';
import { View, Text, FlatList } from 'react-native';
import firebase from 'firebase';

const MyComponent = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 获取Firestore实例
    const firestore = firebase.firestore();

    // 查询集合中的数据
    firestore.collection('myCollection').get()
      .then((querySnapshot) => {
        const results = [];
        querySnapshot.forEach((doc) => {
          // 处理每个文档的数据
          const { name, age } = doc.data();
          results.push({ name, age });
        });
        setData(results);
      })
      .catch((error) => {
        console.error('Error getting documents: ', error);
      });
  }, []);

  return (
    <View>
      <FlatList
        data={data}
        renderItem={({ item }) => (
          <View>
            <Text>Name: {item.name}</Text>
            <Text>Age: {item.age}</Text>
          </View>
        )}
        keyExtractor={(item, index) => index.toString()}
      />
    </View>
