Feature request: Sign up user without creating session

[maxfornacon]

Is your feature request related to a problem? Please describe.
In my use case I want users to sign up, but not get signed in immediately. My application reacts on the AuthChangeEvent, but needs data from the DB that's not immediately present at the time when signUp is called.

Describe the solution you'd like
A possible solution could be adding a createSession parameter. Devs could decide if a session will be created after sign up.

await Supabase.instance.client.auth.signUp(
        password: password,
        email: email,
        createSession: false
    );

Because login credentials are still present I could just call signInWithPassword() after all processing is done to get the session.

Describe alternatives you've considered
Another solution for my user case would be passing a UUID to the signUp method so that I could prefill my user table with all necessary data and then call signUp but assign a self chosen ID to the AuthUser.

I could also create a user with an edge function, but that seems to be unnecessary overhead.

Thanks for the suggestion. Currently, our auth server will create a session when the user signs up, so there needs to be an update on the backend for this feature to land.

There has been requests for this feature, so we will update supabase-flutter once the server side is ready.

Reopening this. The feature is still blocked on a server-side change.

I checked the current supabase/auth (GoTrue) /signup endpoint and there is still no way to sign up a user without creating a session:

• There is no createSession (or equivalent) request parameter or config flag on /signup.
• Session creation is implicit: when autoconfirm is enabled, signup always issues a refresh token and returns a session. A session is only omitted when email/phone confirmation is required.

So supabase-flutter cannot expose a createSession: false option until the server supports it. I've opened a tracking request on the auth server: supabase/auth#2586.

Current workarounds:

• Enable email/phone confirmation, in which case signUp returns the user without a session.
• Create the user via an Edge Function using the admin API.
