payloadAs<T>({required Codec<T, Object?> codec}) → T: Decodes the entire payload as a typed DTO with codec.
payloadJson<T>({required T decode(Map<String, dynamic> payload), String? typeName}) → T: Decodes the entire payload as a typed DTO with a JSON decoder.
payloadValue<T>(String key, {Codec<T, Object?>? codec}) → T?: Returns the decoded payload value for key, or null when it is absent.
payloadValueOr<T>(String key, T fallback, {Codec<T, Object?>? codec}) → T: Returns the decoded payload value for key, or fallback when absent.
