I guess this isn't a flutter project!

let's say you installed flutter correctly and you added the path.

navigate to your folder when you want to create your first flutter project and run cmd in the terminal run, this command flutter create my_first_project or any name you want.

in vs code opens the folder you've just created (my_first_project)and you're good to start.

android emulator must be installed!
