使用image.asset()导入图像时出现的问题

Question

我经常收到这样的错误:

在解析图像编解码器时抛出以下断言:无法加载资源:../images/mall.png

尽管YAML文件是正确的

这是我的pubspec.yaml

environment:
sdk: ">=2.18.0-10.0.dev <3.0.0"

dependencies:
flutter:
sdk: flutter

cupertino_icons: ^1.0.2
dev_dependencies:
flutter_test:
sdk: flutter

flutter_lints: ^2.0.0

# The following section is specific to Flutter packages.
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:
- images/

Answer 1

您的pubspec.yaml应该看起来像这样:

assets:
- images/mall.png
- images/example.png

和

assets:
- images/

添加您需要的所有图像。

Answer 2

在PROJECT DIRECTORY中创建一个名为assets的文件夹不在lib或其他文件夹中。将图像拖放到assets文件夹中。现在是pubspec。Yaml应该是

资产:

• 资产/

Answer 3

我认为您的路径看起来像:

/资产/图片/mall.png

但是你的pubspec。Yaml说它是:

/图片/mall.png

找不到

确保您的文件树与您在pubspec中告诉它的相同。而且不要忘记正确缩进。

说明:

资产:

• 图像/

不代表/assets/images/

应该是:

资产:

• 资产/图片/
