我有一个 Flutter Web 应用程序，它在本地运行良好，但在使用部署后

firebase deploy

图像未显示在网站上，我检查了资产是否已通过跟踪上传，例如 my_app.firebaseapp.com/assets/assets/card.jpg。（并且图像在那里，所以它已经正确上传，但由于某种原因它没有显示在主页本身上）。

网址：https : //websitehostingtry.web.app/#/

https://websitehostingtry.web.app/assets/images/card.jpg

在本地运行相同时：

flutter run -d chrome --release

我的 Pubspec.yaml 文件：

name: website_try
description: A new Flutter project.

version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.3

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:

  uses-material-design: true

  assets:
    - images/

在我的飞镖代码中，我只是更改了默认代码以在计数器之后添加图像...

Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
            Expanded(
              child: Image.network('assets/images/card.jpg'),
            )
          ],
        ), …

我创建了一个flutter web使用网络图像和资产图像的项目，在我的电脑上调试时一切正常，但是当我将其部署到 Web 服务器时，网络图像工作正常，但资产图像根本不显示。当我在 Web 浏览器控制台中检查页面时，出现以下错误：
