[auth] Add login parameter to createUserWithEmailAndPassword()

[jonbhanson]

Currently, when a user creates a new account in auth using email, the user is automatically logged in regardless of whether the email has been verified. It seems most apps are designed to only allow login after the email is verified. Currently, to implement this behavior it is necessary to immediately log the user out after the account is created. This can create stutter if the app uses a StreamBuilder based on the the user stream. For more detail, see this stack overflow thread.

Please add a login parameter to createUserWithEmailAndPassword() to allow the account to be created without logging in the account such as:

createUserWithEmailAndPassword(login: false);

This will save us from the current hacky solution.

This is something we really need guys. Its part of best practice authentication flows...

I agree, but I think it's a bit hard for flutterfire to do this as flutterfire uses the underlying sdks. That means that I think you should create a feature request at the firebase sdk.
