How to add an Item to a Set in Dart ?

In Dart, you can add an item to a Set using the add() method.

In this example,

We create a Set named numbers containing some integer elements.
We use the add() method of numbers to add a new integer element, such as 6, to the set.
Now, numbers contains the added element 6.

var numbers = {1, 2, 3, 4, 5};
numbers.add(6);
print('Numbers: $numbers');

Numbers: {1, 2, 3, 4, 5, 6}

In this example,

We create a Set named fruits containing some string elements.
We use the add() method of fruits to add a new string element, such as 'Orange', to the set.
Now, fruits contains the added element 'Orange'.

var fruits = {'Apple', 'Banana', 'Cherry'};
fruits.add('Orange');
print('Fruits: $fruits');
