I copied all the code and the neccessary directories to this newly created project. Since the original was way old and was giving me error about V2embedding and stuff.

Now I don't understand this error that's been bugging me since 2 days, I am learning Flutter Android app making.

CodePudding user response：

As I can see, it looks like you copy files in wrong directory:

C:\Users\User\StudioProjects\clima\android\app\src\main\res\main\AndroidManifest.xml: 

Usually Manifest file is in android\app\src\main, not in app\src\main\res\main\

In your case AndroidManifest.xml should be in:

C:\Users\User\StudioProjects\clima\android\app\src\main\AndroidManifest.xml: 

Check the paths you copy the code.
