I have a probleme with flutter. I install Android Studio and configure that for flutter (install flutter and Dart) but I can't run my app on any device and android studio console returned:
Unable to locate a development device; please run 'flutter doctor' for information about installing additional components.
and flutter doctor -v :

It's not enough to simply set the ANDROID_SDK_ROOT environment variable. For this to work for me, I had to also do:
flutter config --android-sdk $ANDROID_SDK_ROOT
When I restarted Android studio, it started to work for me
