addAll method - Set class - dart:core library (original) (raw)

description

addAll abstract method

void addAll(

1. Iterable<E> elements )

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

void addAll(Iterable<E> elements);
