Could try running a --verbose flag on the command so I can see the stack trace?

I ran into the same issue, here's the stacktrace:

Can you solve it @ayush221b ?

I think there is a misunderstanding here, according to the readme.

Use a SDK Version
You can use different Flutter SDK versions per project. To do that you have to go into the root of the project and:

fvm use

fvm use specifies the flutter version per project, not globally. Therefore, go to your project root and apply fvm use.
