this is actually an Android studio problem and not Flutter.
Close your IDE then open your project folder and look for .idea open it and look for module.xml. Delete that file and open Android studio again.
It will generate a new *.iml and module.xml files and that error won't be there
You can solve it by closing emulator and restart android studio then from terminal command run (flutter clean) and restart again, run your project and every thing will be ok.
