How to Iterate Over a List with Index in Dart - Step by Step Examples
How to Iterate Over a List with Index in Dart ?
Answer
To iterate over a list in Dart, you can use for-in loops or forEach loops.
✐ Examples
1 Iterate Over List with for-in Loop
In this example,
- We create a List named
numbers
with integer elements. - We use a for-in loop to iterate over the list directly.
- Within the loop, we perform operations on each element or print it.
Dart Program
void main() {
List<int> numbers = [10, 20, 30, 40, 50];
for (int number in numbers) {
print(number);
}
}
Output
10 20 30 40 50
2 Iterate Over List with forEach Loop
In this example,
- We create a List named
names
with string elements. - We use the
forEach
method to iterate over the list. - Within the loop, we perform operations on each element or print it.
Dart Program
void main() {
List<String> names = ["Alice", "Bob", "Charlie", "David"];
names.forEach((name) {
print(name);
});
}
Output
Alice Bob Charlie David
