我的Pubspec.yaml文件

My Pubspec.yaml file

资产:-asset/images/logo.png

assets: - assets/images/logo.png

login.dart代码

login.dart code

new Image.asset("assets/images/logo.png"，宽度:60.0，高度:24.0，适合:BoxFit.cover)

new Image.asset("assets/images/logo.png", width: 60.0, height: 24.0, fit: BoxFit.cover)

目录结构

pubspec.yaml文件

推荐答案

我以错误的方式提到了图像文件.我在'-'和图片名称之间放置空格，而不是Tab.

i mentioned images files in wrong way. i put space between '-' and image name instead of tab.

资产:

- assets/images/logo.png

在pubspec.yaml文件中不要在字符之间放置空格，而不要在制表符之间放置空格

Don't put spaces between the character instead of tab in pubspec.yaml file
