Hey @abraham ,

I'm having trouble getting started with flutter. I run flutter create foo, no issue.

I then go into foo and run flutter run, which gets the error listed below.

I would appreciate your help if possible and whenever you can.

flutter run

What happens when you run flutter doctor?

By the way, running on an emulator seems to work fine from the command line.

I'll have to try again (now that I am at home and not on my work's network) and see if I can run it on my Android device.

Gave it a try, seems like it has to do with my work's network blocking the dependencies for gradle

Interesting. I'd recommend opening an issue with the Flutter team. That's something that flutter doctor should probably test for.
