How to Slice First N Elements from a List in Dart ?

Answer

To slice the first N elements from a list in Dart, you can use the sublist method provided by the List class.

✐ Examples

1 Slice the First N Elements of a List of Integers

In this example,

We create a list named numbers with integer values.
We use the sublist method on the list object numbers to create a new list containing the first N elements.
Finally, we print the sliced list to standard output.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3, 4, 5];
  int n = 3;
  List<int> slicedNumbers = numbers.sublist(0, n);
  print('Sliced list: \$slicedNumbers');
}

Output

Sliced list: [1, 2, 3]

2 Slice the First N Elements of a List of Strings

In this example,

We create a list named words with string values.
We use the sublist method on the list object words to create a new list containing the first N elements.
Finally, we print the sliced list to standard output.

Dart Program

void main() {
  List<String> words = ['apple', 'banana', 'cherry', 'date', 'elderberry'];
  int n = 2;
  List<String> slicedWords = words.sublist(0, n);
  print('Sliced list: \$slicedWords');
}

Output

Sliced list: [apple, banana]
