It looks like adb (the 'Android Debug Bridge') is not able to see your phone. Can you try to see if a new Android app created in Android Studio is able to run on your device?

Regarding the analyzer issue, looks like it's failing on a permission denied issue. Were you inside the directory that contains your Flutter app when you ran flutter analyze?

[ppolasek]

For the flutter analyze issue I was _not_ in the directory containing my Flutter app, and when I did run it from within my app directory I received 'No analyzer warnings! (ran in 8.3s). Likely that was an unrelated issue.

I created a new Android app in Android Studio and accepted the default options, but I was unable to run it due to Error running BeerApp: No target device found. I was wondering if it could be tied to Android File Transfer automatically opening when I plug my phone into my Mac, but even after deleting the app from my Applications directory I'm still unable to run my Android Studio app, and flutter devices also indicates 'no devices'.

[ppolasek]

I finally figured resolved the issue - in USB PC Connection I had previously selected 'Media device (MTP)' on my phone which apparently blocked access from the Mac. When I changed this to 'Send images (PTP)' my device was immediately recognized via 'flutter devices', and I was also able to run my app in Android Studio.
