Kotlin: Listen to auth events

Listen to session changes.

• sessionStatus is a Flow<SessionStatus> that emits the current session status. Everything related to the session is handled by this flow.
• events is a Flow<AuthEvent> that emits auth events. This flow is used to listen to auth events that are independent of the current session, like OTP errors, refresh failures, etc. Experimental.

Examples

Listen to session status changes

supabase.auth.sessionStatus.collect {
    when(it) {
        is SessionStatus.Authenticated -> {
            println("Received new authenticated session.")
            when(it.source) { //Check the source of the session
                SessionSource.External -> TODO()
                is SessionSource.Refresh -> TODO()
                is SessionSource.SignIn -> TODO()
                is SessionSource.SignUp -> TODO()
                SessionSource.Storage -> TODO()
                SessionSource.Unknown -> TODO()
                is SessionSource.UserChanged -> TODO()
                is SessionSource.UserIdentitiesChanged -> TODO()
            }
        }
        SessionStatus.Initializing -> println("Initializing")
        is SessionStatus.RefreshFailure -> {
            println("Session expired and could not be refreshed")
        }
        is SessionStatus.NotAuthenticated -> {
            if(it.isSignOut) {
                println("User signed out")
            } else {
                println("User not signed in")
            }
        }
    }
}

Listen to auth events

supabase.auth.events.collect {
  when(it) {
    is AuthEvent.OtpError ->
      println("Found error in current URL / deeplink during the OAuth flow: ${it.error}")
    is AuthEvent.RefreshFailure -> 
      println("Failed to refresh session: ${it.error}")
  }
}
