SessionManager class final

Manages user authentication state across the application lifecycle.

Extends ChangeNotifier so widgets can rebuild reactively, and also exposes a stateStream for non-widget consumers (e.g. Bloc/Riverpod bridges).

State is persisted across restarts: on construction the manager restores the previous session from SecurePrefs and validates token expiry via TokenStore.

// In main()
final session = SessionManager.instance;
await session.restore();

// In a widget
final session = context.watch<SessionManager>();
if (session.isAuthenticated) { ... }

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
dispose() → void: Discards any resources used by the object.
override
login({required String accessToken, required String refreshToken, String? userId, Map<String, dynamic>? userData}) → Future<void>: Persists tokens and transitions to SessionAuthenticated.
logout() → Future<void>: Clears all tokens, removes persisted session data, and transitions to SessionUnauthenticated.

inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.

Static Properties

instance → SessionManager: Returns the singleton, constructing it with default dependencies on the first call. Override dependencies only for testing via resetForTesting.
no setter

Static Methods

resetForTesting({required TokenStoreBase tokenStore, required SecurePrefsBase securePrefs}) → void: Replaces the singleton with a test double. Call in test setUp.
