I probably did something wrong. When I go to the bin file through cmd and run the commands "flutter" and "flutter doctor" there both run normally. When I am in any other file, for example in C:\, the commands do not run. It happens what I said before, no matter how much time I wait. Why can this be happening? The only other step where I can do a mistake is environment variable setting, but this is quite clear! I'll move on with the setup and I'll see if this is going to affect the app developing procedure.
