Dart Set skipWhile()
Syntax & Examples

Set.skipWhile() method

The `skipWhile` method in Dart returns an Iterable that skips leading elements of the set while the provided test function returns true.

Syntax of Set.skipWhile()

The syntax of Set.skipWhile() method is:

 Iterable<E> skipWhile(bool test(E value))

This skipWhile() method of Set returns an Iterable that skips leading elements while test is satisfied.

Parameters

ParameterOptional/RequiredDescription
testrequiredThe function used to test elements of the set.

Return Type

Set.skipWhile() returns value of type Iterable<E>.


✐ Examples

1 Skip integers less than 3

In this example,

  1. We create a Set set containing integers.
  2. We use the skipWhile() method with a test function that checks if each element is less than 3.
  3. We print the Iterable containing elements after skipping to standard output.

Dart Program

void main() {
  Set<int> set = {1, 2, 3, 4, 5};
  Iterable<int> skippedSet = set.skipWhile((element) => element < 3);
  print('Skipped set elements: $skippedSet');
}

Output

Skipped set elements: (3, 4, 5)

2 Skip strings with length less than 6

In this example,

  1. We create a Set set containing strings.
  2. We use the skipWhile() method with a test function that checks if the length of each string is less than 6.
  3. We print the Iterable containing elements after skipping to standard output.

Dart Program

void main() {
  Set<String> set = {'apple', 'banana', 'orange'};
  Iterable<String> skippedSet = set.skipWhile((element) => element.length < 6);
  print('Skipped set elements: $skippedSet');
}

Output

Skipped set elements: (banana, orange)
