listview横向和纵向组合使用技巧

横向的包一层container,指定高度；
纵向的用Flexible包裹起来；
这两个listview放在一个Column里面就可以了；

import 'package:flutter/material.dart';

void main()=>runApp(MyApp());

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

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text(''),),
      body: Column(
        children: <Widget>[
          Container(
            height: 28,
            child: ListView.builder(
                scrollDirection: Axis.horizontal,
                itemCount: 100,
                itemBuilder: (context, index) {
                  return Card(
                    child: Text('$index'),
                  );
                }),
          ),
          Flexible(
            child: ListView.builder(
                scrollDirection: Axis.vertical,
                itemCount: 100,
                itemBuilder: (context, index) {
                  return Card(
                    child: Text('$index'),
                  );
                }),
          ),

        ],
      ),
    );
  }
}
