Answer

To sort the items of a set in Dart, you can convert the set to a list and then sort the list using the sort() method.

1 Sort Items of an Integer Set

In this example,

We create a set named numbers containing some integer elements using the Set class.
We convert the set to a list using the toList() method.
We sort the list using the sort() method.
Finally, we iterate through the sorted list and print each element to the console.

Dart Program

void main() {
  Set<int> numbers = {5, 3, 1, 4, 2};
  List<int> sortedNumbers = numbers.toList();
  sortedNumbers.sort();
  print('Sorted numbers:');
  for (int number in sortedNumbers) {
    print(number);
  }
}

Output

Sorted numbers:
1
2
3
