Dart vs Kotlin: sets

sets.dart

import 'package:collection/collection.dart';

void main() {
  // Mutable set
  final mutableSet = {1, 2, 3, 3};
  mutableSet.forEach((e) => print(e)); // 1 2 3
  // Empty mutable set
  final emptySet = <int>{};
  // Immutable set (copy of the original)
  final immutableSet = Set.unmodifiable({1, 2, 3});
  // Immutable set view (wrap of the original)
  final immutableSetView = UnmodifiableSetView(mutableSet);
  // Equality
  print({1, 2, 3} == {1, 2, 3}); // false
  print(SetEquality().equals({1, 2, 3}, {1, 2, 3})); // true
  // Creating a set from list
  Set<int> set = Set.from([1, 2, 3, 3]); // {1, 2, 3}
}
