Answer: 
As you can see at the bottom right corner, you don't have an internet connection and thus, it can't reach `github.com`, which it seemingly needs to run.
1. Download a fresh install of flutter sdk and follow the necessary steps from here.. <https://docs.flutter.dev/get-started/install/windows>
2. Be sure to register the path in the environmental variables
3. Be sure to install git
4. Be sure you are connected to the internet along the process

and it should work
