single property

  1. @override
T single

Checks that this iterable has only one element, and returns that element.

Throws a StateError if this is empty or has more than one element. This operation will not iterate past the second element.


T get single {
  final l = length;
  if (l > 1) {
    throw RealmStateError('Too many elements');
  if (l == 0) {
    throw RealmStateError('No element');
  return this[0];
