I am running Flutter 2.2.2 in Terminal.app on macOS Big Sur. I have an Android phone, a Moto G5 Plus running Android 8.1.0. Developer options are on as is USB debugging, and I've connected the phone to my computer with a USB data cable. The device shows up when I run the command flutter devices:
% flutter devices
2 connected devices:
Moto G 5 Plus (mobile) • ZY224TM9NW • android-arm • Android 8.1.0 (API 27)
Chrome (web) • chrome • web-javascript • Google Chrome 91.0.4472.114
However, when I run the command flutter run, it displays the following:
% flutter run
Launching lib/main.dart on Moto G 5 Plus in debug mode...
