magicAuthUserEnricher function

String? magicAuthUserEnricher(Element element, RefRegistry refs)

Enricher: emits magicAuthUser: <id>[:<displayName>] for the authenticated user.

• Returns null when Auth.user() returns null (guest session).
• Emits magicAuthUser: <id>:<displayName> when the user model carries a non-empty display_name attribute.
• Falls back to magicAuthUser: <id> (id only, no trailing colon) when display_name is null, missing, or the empty string.

Implementation

String? magicAuthUserEnricher(Element element, RefRegistry refs) {
  final Model? user = Auth.user<Model>();
  if (user == null) return null;

  final dynamic id = user.getAttribute('id');
  final dynamic raw = user.getAttribute('display_name');
  final String? displayName = (raw is String && raw.isNotEmpty) ? raw : null;

  if (displayName == null) {
    return 'magicAuthUser: $id';
  }
  return 'magicAuthUser: $id:$displayName';
}
