我在react Native中有一个平面列表，但我按下了保存按钮，没有自动重新加载数据

import React, { useState } from 'react';
import { View, Button, FlatList } from 'react-native';

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

  const handleSave = () => {
    // 更新数据源
    const newData = [...data, { id: data.length + 1, name: 'New Item' }];
    setData(newData);
  };

  return (
    <View>
      <Button title="Save" onPress={handleSave} />
      <FlatList
        data={data}
        renderItem={({ item }) => <Text>{item.name}</Text>}
        keyExtractor={(item) => item.id.toString()}
      />
    </View>
  );
};

export default MyComponent;
