take method

  1. @override
Iterable<E> take(
  1. int count
)
override

Creates a lazy iterable of the count first elements of this iterable.

The returned Iterable may contain fewer than count elements, if this contains fewer than count elements.

The elements can be computed by stepping through iterator until count elements have been seen.

The count must not be negative.

Example:

final numbers = <int>[1, 2, 3, 5, 6, 7];
final result = numbers.take(4); // (1, 2, 3, 5)
final takeAll = numbers.take(100); // (1, 2, 3, 5, 6, 7)

Implementation

@override
Iterable<E> take(int count) {
  if (count >= length) {
    return this;
  }
  return _SubRangeIterable(this, 0, count);
}
