How to get Subset from a Set in Dart ?

Answer

To get a subset from a Set in Dart, you can use the where method to filter elements based on a condition.

✐ Examples

1 Get Subset of Even Numbers from a Set

In this example,

We create a Set named numbers and initialize it with some integer elements.
We use the where method on the Set to filter the elements that satisfy a specific condition (in this case, being even).
The where method returns a new Iterable containing only the elements that satisfy the condition.
We convert the Iterable to a Set using the toSet method.
We print the subset to the console to verify the result.

Dart Program

void main() {
  Set<int> numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
  Set<int> evenNumbers = numbers.where((number) => number.isEven).toSet();
  print('Subset of even numbers:');
  for (var number in evenNumbers) {
    print(number);
  }
}

Output

Subset of even numbers:
2
4
6
8
10

2 Get Subset of Numbers Greater Than 5 from a Set

In this example,

We create a Set named numbers and initialize it with some integer elements.
We use the where method on the Set to filter the elements that are greater than 5.
The where method returns a new Iterable containing only the elements that satisfy the condition.
We convert the Iterable to a Set using the toSet method.
We print the subset to the console to verify the result.

Dart Program

void main() {
  Set<int> numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
  Set<int> numbersGreaterThanFive = numbers.where((number) => number > 5).toSet();
  print('Subset of numbers greater than 5:');
  for (var number in numbersGreaterThanFive) {
    print(number);
  }
}

Output

Subset of numbers greater than 5:
6
7
8
9
10
