sublist method

  1. @override
List<T> sublist(
  1. int start, [
  2. int? end
])
override

Returns a new list containing the elements between start and end.

The new list is a List<E> containing the elements of this list at positions greater than or equal to start and less than end in the same order as they occur in this list.

final colors = <String>['red', 'green', 'blue', 'orange', 'pink'];
print(colors.sublist(1, 3)); // [green, blue]

If end is omitted, it defaults to the length of this list.

final colors = <String>['red', 'green', 'blue', 'orange', 'pink'];
print(colors.sublist(3)); // [orange, pink]

The start and end positions must satisfy the relations 0 ≤ start ≤ end ≤ length. If end is equal to start, then the returned list is empty.

Implementation

@override
List<T> sublist(int start, [int? end]) {
  final (normalizedStart, normalizedEnd) =
      _validateAndNormalizeRange(start, end ?? len());
  return _list.sublist(normalizedStart, normalizedEnd);
}
