Properties

ext → Ext?

Ecosystem-defined extension members per SPEC.md §4.5.1.

final

hashCode → int

The hash code for this object.

no setter, inherited

purpose → String?

Producer-declared intent (e.g. "login", "step-up", "sign-out"). Consumers MAY surface this in audit logs or use it to scope the issued nonce. Free-form; ecosystems define the vocabulary.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

subject → String?

The VID the producer intends to authenticate as. Optional — when omitted, the issuer MAY return a subject-agnostic challenge whose binding is established at authenticate time. When present, the issuer SHOULD bind the challenge to this subject so a successful authenticate proves control of THIS VID, not any VID.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

Serialize to a JSON-encodable map, omitting absent members.
