Implementation

@override
set value(Set<T> value) {
  if (value.length < _min || (_max != null && _max < value.length)) {
    throw ArgumentError(
      _max == null
          ? 'The number of elements must be <= $_min.'
          : 'The number of elements must be between $_min and $_max.',
    );
  }

  super.value = {...value};
