Future<void> update([
  1. DocumentReference<Object?>? refe
])

Future<void> update([DocumentReference? refe]) async {
  if (refe != null) {
    if (ref != null) {
      throw 'Document reference is already set';
    }
    ref = refe;
  }
  if (ref == null) {
    throw 'Document reference is null';
  }
  await ref!.set(toMap());
}
