@override Future<DeskDocument> setDefaultDocument(String documentTypeSlug, String documentId)

Atomically unsets the current default for documentTypeSlug and sets documentId as the new default. Returns the updated document.

Implementation

@override
Future<DeskDocument> setDefaultDocument(
  String documentTypeSlug,
  String documentId,
) async {
  // Unset any existing default for this type
  final currentDefault = _documents.values.firstWhereOrNull(
    (d) => d.documentType == documentTypeSlug && d.isDefault,
  );
  if (currentDefault?.id != null) {
    _documents[currentDefault!.id!] = currentDefault.copyWith(
      isDefault: false,
    );
  }

  // Set new default
  final doc = _documents[documentId];
  if (doc == null) {
    throw DeskNotFoundException(
      resourceType: 'Document',
      resourceId: documentId,
    );
  }
  final updated = doc.copyWith(isDefault: true);
  _documents[documentId] = updated;
  return updated;
}
