How to Access Items in a Set in Dart ?

Answer

To access items in a set in Dart, you can use iteration or specific methods provided by the Set class.

✐ Examples

1 Access Items in a Set using Iteration

In this example,

We create a Set named stringSet containing strings.
We use a for loop to iterate over the elements in the set and print each element.

Dart Program

void main() {
  Set<String> stringSet = {"Apple", "Banana", "Orange", "Grapes"};
  
  for (var item in stringSet) {
    print(item);
  }
}

Output

Apple
Banana
Orange
Grapes

2 Access Items in a Set using Specific Methods

In this example,

We create a Set named numberSet containing integers.
We use the contains method to check if an item exists in the set.
We use the length property to get the number of elements in the set.

Dart Program

void main() {
  Set<int> numberSet = {1, 2, 3, 4};
  
  print("Number of elements: ${numberSet.length}");
  print("Does set contain 3? ${numberSet.contains(3)}");
}

Output

Number of elements: 4
Does set contain 3? true
