Examples

Listen to auth changes

final authSubscription = supabase.auth.onAuthStateChange.listen((data) { final AuthChangeEvent event = data.event; final Session? session = data.session; print('event: $event, session: $session'); switch (event) { case AuthChangeEvent.initialSession: // handle initial session case AuthChangeEvent.signedIn: // handle signed in case AuthChangeEvent.signedOut: // handle signed out case AuthChangeEvent.passwordRecovery: // handle password recovery case AuthChangeEvent.tokenRefreshed: // handle token refreshed case AuthChangeEvent.userUpdated: // handle user updated case AuthChangeEvent.userDeleted: // handle user deleted case AuthChangeEvent.mfaChallengeVerified: // handle mfa challenge verified } }); 

Listen to a specific event

final authSubscription = supabase.auth.onAuthStateChange.listen((data) { final AuthChangeEvent event = data.event; if (event == AuthChangeEvent.signedIn) { // handle signIn } }); 

Unsubscribe from auth subscription

final authSubscription = supabase.auth.onAuthStateChange.listen((data) {}); authSubscription.cancel();
