after installing android studio and setting up flutter and dart I've noticed that I can't seem to run anything, when I watch tutorials they always have a green arrow shaped button and some other functionalities, all of which are gray on my screen and don't really do anything. here's a picture...enter image description here
I suspect it has something to do with the 'no devices' but i'm confused because I have an android phone connected to my laptop.
thanks in advance!
