getRange method Null safety
override
Creates an Iterable that iterates over a range of elements.
The returned iterable iterates over the elements of this list
with positions greater than or equal to start and less than end.
The provided range, start and end, must be valid at the time
of the call.
A range from start to end is valid if 0 ≤ start ≤ end ≤ length.
An empty range (with end == start) is valid.
The returned Iterable behaves like skip(start).take(end - start).
That is, it does not break if this list changes size, it just
ends early if it reaches the end of the list early
(if end, or even start, becomes greater than length).
final colors = <String>['red', 'green', 'blue', 'orange', 'pink'];
final firstRange = colors.getRange(0, 3);
print(firstRange.join(', ')); // red, green, blue
final secondRange = colors.getRange(2, 5);
print(secondRange.join(', ')); // blue, orange, pink
Implementation
@override
Iterable<E> getRange(int start, int end) => _base.getRange(start, end);
