Faced the same error for couple of hours, and none of the issue on Github or answer on StackOverflow seems to be working for me.

So after my research I found out that there is no specific reason why Error MSB8066 error occur, but it can be due to space in your project Folder path as mentioned by @aishamhasan or some other undetermined reason. In my case, there is a simple file that is missing.

Error detected in pubspec.yaml:
[   +2 ms]   [        ] No file or variants found for asset: images/project_app.png.

In order to quickly find out what causing this problem, you can run your project from the command line instead of using run functionality on android studio.

flutter run -d windows -v

And inside your verbose, lookout for any error, or you can directly search for Error and then try to figure out what was causing the error.

Followed the same approach and I was able to resolve the error very quickly.
