How can local functions be developed without starter templates?

Hi there, I'm new to Appwrite serverless functions and could use some help developing serverless functions on a self-hosted Appwrite instance. Appwrite is running fine,and I've got the CLI installed, but I can't find a lot of documentation about locally deployed functions. I would like to use recent runtimes for Dart (3.3 or 3.5) and I understand I have to change the environment variables for that. This was mentioned in the Github repo. I think I can get that working. The problem is that git is a real pain to install on my setup and whenever I try to init a function, it gives a git error because it's trying to download starter templates. How can I create and deploy a function completely locally without requiring git for the setup? Sorry if I come across as newbie (which I am regarding functions 😅 ), but can anyone explain this step by step? Thanks in advance for any help.
