一个简单的示例，将图像加载到图块中。

import 'package:flutter/material.dart';void main() {  runApp( MyApp());}class MyApp extends StatelessWidget {  @override  Widget build(BuildContext context) {    return Container(      color: Colors.white30,      child: GridView.count(          crossAxisCount: 4,          childAspectRatio: 1.0,          padding: const EdgeInsets.all(4.0),          mainAxisSpacing: 4.0,          crossAxisSpacing: 4.0,          children: <String>[ 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png', 'http://www.for-example.org/img/main/forexamplelogo.png',          ].map((String url) { return GridTile(     child: Image.network(url, fit: BoxFit.cover));          }).toList()),    );  }}
