ProgramGuruIn 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.
In this example,
numbers containing some integer elements.copiedNumbers by using the spread operator (...) with numbers.copiedNumbers contains a copy of all elements from numbers.void main() {
var numbers = {1, 2, 3, 4, 5};
var copiedNumbers = {...numbers};
print('Copied Numbers:');
copiedNumbers.forEach((number) => print(number));
}Copied Numbers: 1 2 3 4 5
In this example,
fruits containing some string elements.copiedFruits by using the spread operator (...) with fruits.copiedFruits contains a copy of all elements from fruits.void main() {
var fruits = {'Apple', 'Banana', 'Cherry', 'Date'};
var copiedFruits = {...fruits};
print('Copied Fruits:');
copiedFruits.forEach((fruit) => print(fruit));
}Copied Fruits: Cherry Date Banana Apple
