How to Iterate Over a Set in Dart


How to Iterate Over a Set in Dart ?

Answer

To iterate over a set in Dart, you can use the for loop or the forEach method.



✐ Examples

1 Iterate Over Set of Strings Using for Loop

In this example,

  1. We define a set named `mySet` containing string elements.
  2. We use the `for` loop to iterate over the set.
  3. Finally, we execute the loop and process each string item in the set.

Dart Program

void main() {
  // Define set
  Set<String> mySet = {'apple', 'banana', 'orange'};

  // Iterate over set of strings using for loop
  for (String item in mySet) {
    print(item);
  }
}

Output

apple
banana
orange

2 Iterate Over Set of Numbers Using forEach Method

In this example,

  1. We define a set named `mySet` containing numeric elements.
  2. We use the `forEach` method to iterate over the set.
  3. Finally, we execute the method and process each numeric item in the set.

Dart Program

void main() {
  // Define set
  Set<int> mySet = {1, 2, 3, 4, 5};

  // Iterate over set of numbers using forEach method
  mySet.forEach((item) {
    print(item);
  });
}

Output

1
2
3
4
5
