If you're using the command line tool without android studio been installed todevelop mobile app here's a way around this issue I was able to resolve it.

First check if there are packages to be updated

sdkmanager --list

if there are then run the command below ensure you've good internet connection and power

sdkmanager --update

Next run

sdkmanager --install "cmdline-tools;latest"

Next run the command below and the error will not be there again.

flutter doctor --android-licenses

flutter doctor 

and you're good to go!!!
