✐ Examples

1 Checking if any number is even

In this example,

  1. We create a List numbers with values [1, 2, 3, 4, 5].
  2. We use the any() method with a test function that checks if an element is even.
  3. We print the result, which indicates if any number in the list is even.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3, 4, 5];
  bool isAnyEven = numbers.any((element) => element.isEven);
  print(isAnyEven);
}

Output

true

2 Checking for short words

In this example,

  1. We create a List words with values ['apple', 'banana', 'cherry'].
  2. We use the any() method with a test function that checks if a word's length is less than 5.
  3. We print the result, which indicates if there's any short word in the list.

Dart Program

void main() {
  List<String> words = ['apple', 'banana', 'cherry'];
  bool hasShortWord = words.any((element) => element.length < 5);
  print(hasShortWord);
}

Output

true
