addAll method

  1. @override
void addAll(
  1. Iterable<E> elements
)
override

Adds all elements to this set.

Equivalent to adding each element in elements using add, but some collections may be able to optimize it.

final characters = <String>{'A', 'B'};
characters.addAll({'A', 'B', 'C'});
print(characters); // {A, B, C}

Implementation

@override
void addAll(Iterable<E> elements) {
  value.addAll(elements);
  refresh();
}
