如何在flutter中使用SingleChildScrollView中的Listview？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter ListView in SingleChildScrollView'),
        ),
        body: SingleChildScrollView(
          child: Column(
            children: <Widget>[
              ListView.builder(
                shrinkWrap: true,
                physics: NeverScrollableScrollPhysics(),
                itemCount: 20,
                itemBuilder: (BuildContext context, int index) {
                  return ListTile(
                    title: Text('Item $index'),
                  );
                },
              ),
            ],
          ),
        ),
      ),
    );
  }
}
