如何让Flatlist将项目滚动到%1

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

const data = [
  { id: 1, name: 'Item 1' },
  { id: 2, name: 'Item 2' },
  { id: 3, name: 'Item 3' },
  // 更多数据...
];

const App = () => {
  const flatListRef = useRef(null);

  const scrollToOffset = (offset) => {
    flatListRef.current.scrollToOffset({ offset, animated: true });
  };

  return (
    <View>
      <Button title="Scroll to 50%" onPress={() => scrollToOffset(data.length * 0.5)} />
      <FlatList
        ref={flatListRef}
        data={data}
        keyExtractor={(item) => item.id.toString()}
        renderItem={({ item }) => <Item name={item.name} />}
      />
    </View>
  );
};

const Item = ({ name }) => (
  // 列表项的渲染逻辑
);

export default App;
