To initialize a set in Dart, you can use the Set literal or the Set constructor.
In this example,
mySet
.mySet
with a set literal {}
containing initial elements.mySet
using set operations such as adding elements, removing elements, and checking for membership.var mySet = {"apple", "banana", "orange"};
// mySet is now initialized with elements "apple", "banana", and "orange"
// Example usage:
// Add elements to the set
mySet.add("kiwi");
// Remove elements from the set
mySet.remove("banana");
// Check if an element is present in the set
bool containsElement = mySet.contains("apple");
print("Is element 'apple' present in the set: $containsElement");
Is element 'apple' present in the set: true
In this example,
emptySet
.emptySet
using the default constructor Set()
.emptySet
using set operations such as adding elements, removing elements, and checking for membership.var emptySet = Set<String>();
// emptySet is now initialized as an empty set
// Example usage:
// Add elements to the set
emptySet.add("apple");
// Remove elements from the set
emptySet.remove("apple");
// Check if an element is present in the set
bool containsElement = emptySet.contains("apple");
print("Is element 'apple' present in the set: $containsElement");
Is element 'apple' present in the set: false
