我插入了6张卡，但是无法滚动屏幕 .

根据下图，页脚中出现红色条纹，屏幕不滚动 .

有什么可以滚动屏幕？

main.dart

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: "Myapp",
      home: new HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) => new Scaffold(
    appBar: new AppBar(
      backgroundColor: new Color(0xFF26C6DA),
    ),
    body: new Column(
      children: <Widget>[
        new Card(
          child: new Column(
            mainAxisSize: MainAxisSize.min,
            children: <Widget>[
              const ListTile(
                leading: const Icon(Icons.album),
                title: const Text('The Enchanted Nightingale'),
                subtitle: const Text('Music by Julie Gable. Lyrics by Sidney Stein.'),
              ),
            ],
          ),
        ),
        ...
        ...
        ...
      ],
    )    
  );
}

    列不滚动 . 尝试使用ListView替换外部列 . 你可能需要把shrinkWrap：true放在上面 .

    列中的列使得无需设置高度就无法计算布局 . 第二列是无用的，因为它只包含一个元素，尝试将ListTile直接作为卡的主体 .

    你必须把它放在ListView.builder上

    ListView.builder(
    itemBuilder: (BuildContext context, int index){
    final item = yourItemLists[index];
    new Card(
      child: new Column(
        mainAxisSize: MainAxisSize.min,
        children: <Widget>[
          const ListTile(
            leading: const Icon(Icons.album),
            title: const Text('The Enchanted Nightingale'),
            subtitle: const Text('Music by Julie Gable. Lyrics by Sidney Stein.'),
          ),
        ],
      ),
    );
  },
  itemCount: yourItemLists.length,
);

    要使列可滚动，只需将其包装在SingleChildScrollView中 .
