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

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
