Flutter开发：ListView动态获取数据源

模拟数据：

在工程目录下添加一个ListDart文件模拟存放我们的数据源，然后在Main.dart文件中引入该文件

List listData=[
      {
          "title": 'Candy Shop',
          "author": 'Mohamed Chahin',
          "imageUrl": 'https://www.itying.com/images/flutter/1.png',
      },
       {
          "title": 'Childhood in a picture',
          "author": 'Google',
          "imageUrl": 'https://www.itying.com/images/flutter/2.png',
      },
      {
          "title": 'Alibaba Shop',
          "author": 'Alibaba',
          "imageUrl": 'https://www.itying.com/images/flutter/3.png',
      },
      {
          "title": 'Candy Shop',
          "author": 'Mohamed Chahin',
          "imageUrl": 'https://www.itying.com/images/flutter/4.png',
      },
       {
          "title": 'Tornado',
          "author": 'Mohamed Chahin',
          "imageUrl": 'https://www.itying.com/images/flutter/5.png',
      },
      {
          "title": 'Undo',
          "author": 'Mohamed Chahin',
          "imageUrl": 'https://www.itying.com/images/flutter/6.png',
      },
      {
          "title": 'white-dragon',
          "author": 'Mohamed Chahin',
          "imageUrl": 'https://www.itying.com/images/flutter/7.png',
      }      

  ];

import 'res/listData.dart';

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
        itemCount: listData.length,
        padding: EdgeInsets.all(10),
        itemBuilder: getItem);
  }

  Widget getItem(context, index) {
    return ListTile(
      title: Text(listData[index]['title']),
      subtitle: Text(listData[index]['author']),
      leading: Image.network(listData[index]['imageUrl']),
    );
