如果数据已更新，则不更新FlatList

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

const MyComponent = () => {
  const [data, setData] = useState([
    { key: '1', name: 'Item 1' },
    { key: '2', name: 'Item 2' },
    { key: '3', name: 'Item 3' },
  ]);

  const updateData = () => {
    // 模拟数据更新
    const newData = [
      { key: '1', name: 'Updated Item 1' },
      { key: '2', name: 'Updated Item 2' },
      { key: '3', name: 'Updated Item 3' },
    ];
    setData(newData);
  };

  return (
    <View>
      <FlatList
        data={data}
        renderItem={({ item }) => <Text>{item.name}</Text>}
      />
      <Button title="Update Data" onPress={updateData} />
    </View>
  );
};

export default MyComponent;
