我在窗口系统中创建了一个颤振项目。它正在运行，窗口中有任何错误。然后我在ubuntu上运行了同样的项目。我面对的是某种没有发现的路径错误。这些方法我都试过了。
- 运行:'pub clean'命令
- 运行在此命令中发现的:'flutter doctor' 0问题
- 创建了一个新项目，并将所有lib文件夹放入ubuntu的新项目中我在控制台日志中遇到这些错误。
在代码编辑器IntelliJ中没有任何错误显示，我也在Android Studio上尝试过。我在过去的2-3周内找到了解决方案。但没有找到解决办法。这是控制台部分。
控制台日志:

问题是它会使用你创建的windows路径
我想这也许能解决你的问题。
在终端中打开项目文件夹路径并运行以下命令:
flutter clean
一旦完成,
执行命令
flutter pub get
如果它不能解决你的问题，在ubuntu中创建一个新项目，复制你项目中的lib文件夹，并替换新项目中的lib文件夹。
