@Teovald, we may need to update the code that tries to auto-locate android studio; we look in a few common platform specific locations. In the meantime, you can fix likely fix the issue by running flutter config --android-studio-dir <path/to/android/studio>.

@mit, we should update our getting started docs for this

Hi @devoncarew, thanks for the quick answer !

Switching to the alpha branch of flutter solved the issue : ultimately it sounds like I don't need to use AS (another issue is that I don't see flutter in the list of plugins I can install for any version of Android Studio), I just needed the gradle wrapper and the last versions of flutter have switched to it.

On my end, AS is installed in /Applications/Android Studio 2.3.app . I guess if you only look for Android Studio.app, you are not going to find it.
IMO this kind of setup is probably fairly common : many android devs have several AS versions installed at the same time.
