getRange method
Returns an Iterable that iterates over the objects in the range
start inclusive to end exclusive.
The provided range, given by start and end, must be valid at the time
of the call.
A range from start to end is valid if 0 <= start <= end <= len, where
len is this list's length. The range starts at start and has length
end - start. An empty range (with end == start) is valid.
The returned Iterable behaves like skip(start).take(end - start).
That is, it does not throw if this list changes size.
List<String> colors = ['red', 'green', 'blue', 'orange', 'pink'];
Iterable<String> range = colors.getRange(1, 4);
range.join(', '); // 'green, blue, orange'
colors.length = 3;
range.join(', '); // 'green, blue'
Implementation
Iterable<E> getRange(int start, int end);
