ProgramGuruTo check if a specific item is present in a Set in Dart, you can use the contains method of the Set class.
In this example,
Set named numbers and initialize it with some integer elements.itemToCheck with the value of the item we want to check for.contains method of the numbers set to check if itemToCheck is present in the set.contains method returns a boolean value: true if the item is present, and false if it is not.void main() {
Set<int> numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int itemToCheck = 5;
bool containsItem = numbers.contains(itemToCheck);
print('Does the set contain $itemToCheck? $containsItem');
}Does the set contain 5? true
In this example,
Set named fruits and initialize it with some string elements.itemToCheck with the value of the item we want to check for.contains method of the fruits set to check if itemToCheck is present in the set.contains method returns a boolean value: true if the item is present, and false if it is not.void main() {
Set<String> fruits = {'apple', 'banana', 'cherry', 'date', 'fig'};
String itemToCheck = 'cherry';
bool containsItem = fruits.contains(itemToCheck);
print("Does the set contain '$itemToCheck'? $containsItem");
}Does the set contain 'cherry'? true
