Android studio gets error on fresh flutter app

Question

When I try to run my flutter app from inside android studio I get the following output:

Ok, so that doesn't work. But if I run "flutter run" from the command line, the app loads.

Uninstalling old version..

I'm thinking the error complaining about "remote: no space left on device" may have something to do with it. I've certainly had no luck searching for the errors that android studio is throwing when it tries to build. But as far as I can tell, neither my computer's root drive, nor the android device, are out of space? And if that's the case, WHY DOES IT STILL WORK? And how do I get it to work inside android studio?

Since I've gone through all the trouble of installing the monstrosity that is android studio, I'd like it if it actually RAN.

Please note that this is a brand-new project. I've deleted comments, but not actually changed any of the dart code yet. Maybe I generated it wrong?

Edit: I fail to see how a compile-time error could be caused by the particular runtime environment, but it's a crazy world we live in. So I wiped and reset my emulated device anyway. Same error. Just for giggles, I shut it off, plugged in my physical phone, and tried to compile it for my phone. Same thing again.

Answer 1

You've probably run the dart file with the dart icon instead of the Flutter icon.

You can access this menu from the Run dropdown menu in android studio's toolbar.

Answer 2

Another way to solve this is to go to Edit Configuration in the Run tab, then add a new entry the ( + ) plus sign to add a new configuration, then tap flutter and select path to the package you're using in this case main.dart. Save and run this main.dart that you created.
