I have installed flutter, git, android studio recently and was trying to run flutter commands after setting path in environment variables but I am getting following error :

fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' Manage your Flutter app development.

I will be more than happy if I will get a solution to this problem since I am struggling to get one from past few days.
thank you !

its :
flutter
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
Manage your Flutter app development.

Sorry it is impossible to guess what is happening there. I would guess that your installation, or setup, is incorrect. I suggest you check what you have done against the Flutter documentation.
