Hi there! Thanks for proposing this

It was very hard to find documentation related to it, the Java + Objective-C documents did not mention it but I found it in the Javascript SDK docs: https://firebase.google.com/docs/reference/js/firebase.User#updateprofile

So I see two issues:

• could you also update the type for the user name? It shares this clearing style
• could you update the documentation for the parameters? e.g. from "An optional photo URL for the user. Not passing it leaves it unchanged. Passing null clears the value"

@andreibarabas - a quick tweak of the PR in response to the feedback and we can merge this I think!

[mikehardy]

I patched it up for you

Good to go pending CI queue clearing after #4209 is resolved
