✐ Examples

1 Taking elements from a list of numbers

In this example,

  1. We create a list numbers containing integers.
  2. We use the take() method to take the first 3 elements.
  3. We convert the resulting Iterable to a list and print it.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3, 4, 5];
  Iterable<int> taken = numbers.take(3);
  print(taken.toList());
}

Output

[1, 2, 3]

2 Taking elements from a list of strings

In this example,

  1. We create a list words containing strings.
  2. We use the take() method to take the first 2 elements.
  3. We convert the resulting Iterable to a list and print it.

Dart Program

void main() {
  List<String> words = ['apple', 'banana', 'cherry'];
  Iterable<String> taken = words.take(2);
  print(taken.toList());
}

Output

[apple, banana]

3 Taking elements from a set of numbers

In this example,

  1. We create a set uniqueNumbers containing integers.
  2. We use the take() method to take the first element.
  3. We convert the resulting Iterable to a list and print it.

Dart Program

void main() {
  Set<int> uniqueNumbers = {1, 2, 3};
  Iterable<int> taken = uniqueNumbers.take(1);
  print(taken.toList());
}

Output

[1]
