setRange method

void setRange(int start, int end, Iterable<E> iterable, [ int skipCount = 0 ])

Copies the objects of iterable, skipping skipCount objects first, into the range start, inclusive, to end, exclusive, of the list.

List<int> list1 = [1, 2, 3, 4];
List<int> list2 = [5, 6, 7, 8, 9];
// Copies the 4th and 5th items in list2 as the 2nd and 3rd items
// of list1.
list1.setRange(1, 3, list2, 3);
list1.join(', '); // '1, 8, 9, 4'

The provide range, given by start and end, must be valid. 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 iterable must have enough objects to fill the range from start to end after skipping skipCount objects.

If iterable is this list, the operation copies the elements originally in the range from skipCount to skipCount + (end - start) to the range start to end, even if the two ranges overlap.

If iterable depends on this list in some other way, no guarantees are made.
