no setter, inherited

onChallenge → Stream<Extra>

When the challenge starts the stream will provide the current Extra in case the client needs some additional information to challenge the server.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

secret ↔ String

getter/setter pair

final

Methods

cancelPendingChallenge() → Future<void>

Cancels work associated with the current authentication attempt.

inherited

challenge(Extra extra) → Future<Authenticate>

Called when the router sends a challenge (CHALLENGE frame).

override

dispose() → Future<void>

Releases authentication-method resources.

inherited

getName() → String

override

hello(String? realm, Details details) → Future<void>

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

inherited

verifyFinal({required String? authId, required String? authMethod, required Map<String, Object?>? authExtra}) → Future<void>

Verifies authentication data returned by the router before session use.
