Flutter无法从网址加载图片

Question

当我尝试从一个网址中加载图片时,我遇到了一个巨大的错误.我已将其上传到hastebin:https://hastebin.com/iguvopihog.m

这是我的代码:

import 'package:flutter/material.dart';
import 'package:test/news.dart';

void main() => runApp(new Main());

class Main extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Test',
      home: new Scaffold(
        body: new Image.network('www.google.de/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png'),
        appBar: new AppBar(
          title: new Text("Test"),
          actions: <Widget>[
            new IconButton(icon: new Icon(Icons.menu), onPressed: null),
          ],
        ),
      ),
    );
  }
}

Answer 1

出于某种原因,Image.network似乎将URL解释为文件路径.

尝试明确地设置协议:

body: new Image.network('http://www.google.de/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png'),
