我是一个完全的初学者，尝试对自己进行一半的学习，所以请逐步提供建议。
我正在尝试在Windows上使用Android Studio和Flutter制作应用。当我尝试通过模拟器运行我的应用程序时（我使用genymotion，因为我有Ryzen cpu），这是控制台的内容：
Invalid depfile: C:\Users\me\AndroidStudioProjects\i_am_rich\.dart_tool\flutter_build\483fc1f7e1eeed45c31ebc61a3e78ae0\kernel_snapshot.d

当我在控制台中运行Flutter Doctor时：
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.12.13+hotfix.7, on Microsoft Windows [Version 10.0.18363.592], locale
en-AU)
[√] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
[√] Android Studio (version 3.5)
[√] Connected device (1 available)
• No issues found!
当我尝试扑干净时：
Error: No pubspec.yaml file found.
This command should be run from the root of your Flutter project.
Do not run this command from the root of your git clone of Flutter.
我的Flutter控制台位于C：\ src \ flutter \ flutter。我真的不知道我在做什么或如何解决这个问题，我感到有些沮丧！任何建议将是美好的。谢谢。
要使用flutter clean，请将您自己（cd ..）重定向到pubspec.yaml文件所在的文件夹中。我目前正面临着同样的问题，但这消除了“无效的Deepfile”问题。
