intersection<T> function Set operations

Set<T> intersection<T>(Iterable<T> iterable, Iterable<Iterable<Object?>> others)

Returns a new set containing every (distinct) value that appears in all of the given iterables.

The order of values in the returned set is based on their first occurrence in the given iterables.

intersection([0, 2, 1, 0], [[1, 3]]); // {1}

Implementation

Set<T> intersection<T>(
    Iterable<T> iterable, Iterable<Iterable<Object?>> others) {
  var set = Set.of(iterable);
  for (final other in others) {
    set = set.intersection(Set.of(other));
  }
  return set;
}
