How to Remove Specific Item from a Set in Dart - Step by Step Examples

How to Remove Specific Item from a Set in Dart ?

To remove a specific item from a set in Dart, you can use the remove method to delete the item from the set.

In this example,

We create a Set named numberSet using the {} syntax, which contains integer values 1, 2, 3, 4, and 5.
We use the remove method of numberSet to remove the item 3 from the set.
Finally, we print the modified set numberSet to see the removed item.

void main() {
  Set<int> numberSet = {1, 2, 3, 4, 5};
  numberSet.remove(3);

  print(numberSet);
}

{1, 2, 4, 5}

In this example,

We create a Set named stringSet using the {} syntax, which contains string values 'apple', 'banana', 'cherry', 'date', and 'grape'.
We use the remove method of stringSet to remove the item 'cherry' from the set.
Finally, we print the modified set stringSet to see the removed item.

void main() {
  Set<String> stringSet = {'apple', 'banana', 'cherry', 'date', 'grape'};
  stringSet.remove('cherry');

  print(stringSet);
}

{'apple', 'banana', 'date', 'grape'}
