Flutter:如何制作长于一个屏幕的窗体

import 'package:flutter/material.dart';

class LongForm extends StatefulWidget {
  @override
  _LongFormState createState() => _LongFormState();
}

class _LongFormState extends State<LongForm> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Long Form'),
      ),
      body: ListView(
        children: <Widget>[
          // 在这里添加需要显示的内容
        ],
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: LongForm(),
  ));
}
