sublist method Null safety

  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.

var colors = ["red", "green", "blue", "orange", "pink"];
print(colors.sublist(1, 3)); // [green, blue]

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

print(colors.sublist(1)); // [green, blue, orange, pink]

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

Implementation

@override
List<T> sublist(int start, [int? end]) {
  _context.enforceReadPolicy(_atom);

  _atom.reportObserved();
  return _list.sublist(start, end);
}
