I am using supabase and flutter and I need to implement SSO with an OpenID (OIDC) provider that is not supported out of the box from supabase. As Facebook and some other standard providers use OIDC under the hood, I expect it should be possible. But in the UI I can only see SAML 2.0 but no OIDC.
I found this communtiy question. But also this issue which was closed after merging a PR. But even with this issue closed I am not sure how to implement it in flutter. I couldn't find any example code whatsoever. Could anyone guide me? Thanks a lot!
