bitteNo, I mean, from within whatever file manager you are using (E.g. Explorer, Finder, whatever), move the folder from its current location to wherever you would like it to be. There is nothing inherently special about the current location of your project. It can be cut/pasted like any other folder or file on your computer. (Just to be clear, you are talking about YOUR project and not the flutter SDK folder... right? That would be a different story)
bitteBut if it does make the folder relative to where you currently care, just 'cd' into whatever directly you want to create the project, and then run flutter create
bittesorry, typo. Meant to say "'cd' into whatever directory* you want to create the project in"
