How to Slice Last N Elements from a List in Dart - Step by Step Examples



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

Answer

To slice the last N elements from a list in Dart, you can use list slicing with negative indices.



✐ Examples

1 Slice the Last N Elements of a List of Integers

In this example,

  1. We create a list named numbers with integer values.
  2. We use list slicing with negative indices numbers.sublist(numbers.length - n) to slice the last N elements.
  3. 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(numbers.length - n);
  print('Sliced list: \$slicedNumbers');
}

Output

Sliced list: [3, 4, 5]

2 Slice the Last N Elements of a List of Strings

In this example,

  1. We create a list named words with string values.
  2. We use list slicing with negative indices words.sublist(words.length - n) to slice the last N elements.
  3. 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(words.length - n);
  print('Sliced list: \$slicedWords');
}

Output

Sliced list: [date, elderberry]

Summary

In this tutorial, we learned How to Slice Last N Elements from a List in Dart language with well detailed examples.
