Im not sure but I think for flutter commands to work, git is one of the requirements so i think along with github desktop, git CLI should also be installed. It wont affect anything even if we install git but maybe it can if its not installed.

Yes, as most probably everyone use their own path but I think it might be helpful just for reference

I also installed git long time ago so not sure about this but I think its important to mention that the path should be added to environment variables just in case someone faces error regarding it.

i added this infos for git path in setup, i was only surprised that my env was updated.
