Thanks very much for the PR, @abicorios. It looks like the code in the related page (https://www.dartlang.org/tutorials/dart-vm/cmdline) has been updated, but not necessarily the text, and not the downloadable code (in this repo).

I'm inclined to accept your PR, even though we do say on the page that it hasn't been updated for Dart 2, and we should have a better solution for updating the code in this repo.

Unfortunately, our CLA checker doesn't recognize your signature. Did you use the same email account to sign as is associated with your GitHub account?

@kwalrath, I used the web interface of the Github to do the commit, and I had the private e-mail in settings. Now I change the e-mail status to the public.
