Dart – Set

Set

A set is an unordered collection of values. We can’t get the values by their index values as they are unordered. Values in set are unique i.e. they can’t be repeated.

• Creating a Set using a constructor:

void main() {
  Set<int> set = Set();
}

• Creating a Set using List

void main() {
  List<int> list = [1, 2, 3, 4];
  Set<int> set = Set.from(list);
}

• Inserting elements in Set

void main() {
  List<int> list = [1, 2, 3, 4];
  Set<int> set = Set.from(list);
  set.add(5);
  set.add(6);
}
