How to Iterate Over a Set in Dart - Step by Step Examples
How to Iterate Over a Set in Dart ?
Answer
To iterate over a set in Dart, you can use the for loop or the forEach method.
✐ Examples
1 Iterate Over Set of Strings Using for Loop
In this example,
- We define a set named `mySet` containing string elements.
- We use the `for` loop to iterate over the set.
- Finally, we execute the loop and process each string item in the set.
Dart Program
void main() {
// Define set
Set<String> mySet = {'apple', 'banana', 'orange'};
// Iterate over set of strings using for loop
for (String item in mySet) {
print(item);
}
}
Output
apple banana orange
2 Iterate Over Set of Numbers Using forEach Method
In this example,
- We define a set named `mySet` containing numeric elements.
- We use the `forEach` method to iterate over the set.
- Finally, we execute the method and process each numeric item in the set.
Dart Program
void main() {
// Define set
Set<int> mySet = {1, 2, 3, 4, 5};
// Iterate over set of numbers using forEach method
mySet.forEach((item) {
print(item);
});
}
Output
1 2 3 4 5
