Allow users to authenticate in the app using Google and Apple.

[yatendra2001]

Problem

Currently, the app only accepts email sign-in/signup. Having OAuth would be better for the user as they can sign in with ease.

Proposed solution

We can create a google and apple OAuth depending on the platform at the login-page.

Additional context

We can implement this feature using google_sign_in and apple_sign_in packages from pub dev along with the firebase.
We can do this using flutter_appauth as well.

But I need to understand the backend first to implement this feature because if the user is existing then we won't direct him to the signup page for asking for their username and other mandatory processes.

I would like to work on this @teolemon , do you think it's feasible?

[M123-dev]

As fat as I know there is already some work going for a new authentication System on the server, which will very likely also support OAuth, but I don't know what the current progress is

[yatendra2001]

So what do you suggest?
Should I try to implement it based on current progress?

[M123-dev]

There should be definitely some coordination with the people working on the backend. Though I don't know who is working on this
