如何从JSON文件中随机获取并将其呈现为FlatList？

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

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

  useEffect(() => {
    // 读取JSON文件
    RNFS.readFile('/path/to/json/file.json')
      .then((content) => {
        // 将文件内容转换为JavaScript对象
        const jsonData = JSON.parse(content);

        // 从JavaScript对象中随机获取数据
        const randomData = getRandomData(jsonData);

        // 更新数据状态
        setData(randomData);
      })
      .catch((error) => {
        console.log(error);
      });
  }, []);

  // 从JavaScript对象中随机获取数据
  const getRandomData = (jsonData) => {
    const keys = Object.keys(jsonData);
    const randomKey = keys[Math.floor(Math.random() * keys.length)];
    return jsonData[randomKey];
  };

  // 渲染每个列表项
  const renderItem = ({ item }) => (
    <View>
      <Text>{item.title}</Text>
      <Text>{item.description}</Text>
    </View>
  );

  return (
    <FlatList
      data={data}
      renderItem={renderItem}
      keyExtractor={(item) => item.id.toString()}
    />
  );
};

export default MyComponent;
