Flutter -如何在一个页面中显示两个相连的列表？

import 'package:flutter/material.dart';

class MyPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Two Connected Lists'),
      ),
      body: Container(
        child: Column(
          children: [
            Expanded(
              child: ListView.builder(
                itemCount: list1.length,
                itemBuilder: (context, index) {
                  return ListTile(
                    title: Text(list1[index]),
                  );
                },
              ),
            ),
            Expanded(
              child: ListView.builder(
                itemCount: list2.length,
                itemBuilder: (context, index) {
                  return ListTile(
                    title: Text(list2[index]),
                  );
                },
              ),
            ),
          ],
        ),
      ),
    );
  }
}

List<String> list1 = ['Item 1', 'Item 2', 'Item 3'];
List<String> list2 = ['Item A', 'Item B', 'Item C'];
