颤动图像不显示：“无法加载资源”

Question

我没有在应用程序中看到我的图像，而是看到一个带有 X 的红色框，上面写着Unable to load asset: images/aboutmaggie.png.

我创建了一个assets带有子目录的目录images。该目录assets与 处于同一级别pubspec.yaml。

我将图像放入images目录中。当我在 Android Studio 中单击图像时，图像就会显示。

在pubspec.yaml我有这些行：

flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/

我添加了

flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/

我跑了flutter pub get。我运行了“工具”>“颤振”>“颤振清洁”。我关闭并重新启动 Android Studio。

错误信息是：

======== Exception caught by image resource service ================================================
The following assertion was thrown resolving an image codec:
Unable to load asset: images/aboutmaggie.png

我尝试将另一个图像放入assets/images并调用它，但第二个图像也不会加载。

这张照片有什么问题吗？

Answer 1

调用图像时出错，

更改代码中的这一行

Image.asset('images/aboutmaggie.png')

到这一行

Image.asset('assets/images/aboutmaggie.png')

我希望这有帮助，谢谢
