如何更改SectionList节索引的首选项？

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

const data = [
  { title: 'A', data: ['Apple', 'Apricot', 'Avocado'] },
  { title: 'B', data: ['Banana', 'Blueberry', 'Blackberry'] },
  { title: 'C', data: ['Cherry', 'Coconut', 'Cranberry'] },
];

const renderItem = ({ item }) => (
  <View style={{ padding: 10 }}>
    <Text>{item}</Text>
  </View>
);

const renderSectionHeader = ({ section }) => (
  <View style={{ backgroundColor: 'lightgray', padding: 10 }}>
    <Text style={{ fontWeight: 'bold' }}>{section.title}</Text>
  </View>
);

const App = () => (
  <SectionList
    sections={data}
    renderItem={renderItem}
    renderSectionHeader={renderSectionHeader}
  />
);

export default App;
