Error while debugging first app in flutter using a real device

Question

I'm using VS code without Android studio in Ubuntu 20.04. While running the first app in flutter in debugging mode in an real device produced this error given below. I also tried to change my JDK version but it didn't worked.

Launching lib/main.dart on Nokia 6 1 Plus in debug mode...

FAILURE: Build failed with an exception.

Your gradle sync has failed for some reason. Do this

File > Open
Navigate to your project
You will see an android folder there open that as project in a new window
Check the gradle sync issues and resolve those
