React Native获取SectionList中的第一行

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

const sections = [
  { title: 'Group 1', data: ['Item 1', 'Item 2', 'Item 3'] },
  { title: 'Group 2', data: ['Item 4', 'Item 5', 'Item 6'] },
];

class MySectionList extends Component {
  render() {
    return (
      <SectionList
        sections={sections}
        renderItem={({ item }) => <Text>{item}</Text>}
        renderSectionHeader={({ section }) => (
          <View>
            <Text>{section.title}</Text>
          </View>
        )}
      />
    );
  }
}

const firstItem = sections[0].data[0];
console.log(firstItem); // 输出：'Item 1'
