How to Copy a Set in Dart - Step by Step Examples

How to Copy a Set in Dart ?

Answer

In Dart, you can create a copy of a set by using the spread operator (...) to create a new set with the same elements as the original set.

✐ Examples

1 Copy Integer Set

In this example,

We create a set named numbers containing some integer elements.
We create a new set named copiedNumbers by using the spread operator (...) with numbers.
Now, copiedNumbers contains a copy of all elements from numbers.

Dart Program

void main() {
  var numbers = {1, 2, 3, 4, 5};
  var copiedNumbers = {...numbers};

  print('Copied Numbers:');
  copiedNumbers.forEach((number) => print(number));
}

Output

Copied Numbers:
1
2
3
4
5

2 Copy String Set

In this example,

We create a set named fruits containing some string elements.
We create a new set named copiedFruits by using the spread operator (...) with fruits.
Now, copiedFruits contains a copy of all elements from fruits.

Dart Program

void main() {
  var fruits = {'Apple', 'Banana', 'Cherry', 'Date'};
  var copiedFruits = {...fruits};

  print('Copied Fruits:');
  copiedFruits.forEach((fruit) => print(fruit));
}

Output

Copied Fruits:
Cherry
Date
Banana
Apple
