尝试同时使用NetworkImage和Image.network()方法从Web加载jpg图像，在这两种情况下，它都显示存在“ImageCodecException”，并且它是“Fialed to load network image”。已在DartPad中尝试。此代码：

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      
      home: Scaffold(
        body:
            // Load image from network
            new Image.network(
              'https://www.nasa.gov/images/content/162056main_PIA08329.jpg'),
            ),
   );
  }

}
