ProgramGuruTo check if a set contains all the items of another set in Dart, you can use the containsAll method of the Set class.
In this example,
setA and setB and initialize them with some integer elements.containsAll method of setA to check if all elements in setB are also present in setA.containsAll method returns a boolean value: true if setA contains all elements of setB, and false otherwise.setA contains all elements of setB.void main() {
Set<int> setA = {1, 2, 3, 4, 5};
Set<int> setB = {2, 3};
bool containsAll = setA.containsAll(setB);
print('Does setA contain all elements of setB? $containsAll');
}Does setA contain all elements of setB? true
In this example,
setA and setB and initialize them with some string elements.containsAll method of setA to check if all elements in setB are also present in setA.containsAll method returns a boolean value: true if setA contains all elements of setB, and false otherwise.setA contains all elements of setB.void main() {
Set<String> setA = {'apple', 'banana', 'cherry'};
Set<String> setB = {'banana', 'cherry'};
bool containsAll = setA.containsAll(setB);
print('Does setA contain all elements of setB? $containsAll');
}Does setA contain all elements of setB? true
