rangeInt function

List<int> rangeInt(
  1. int start,
  2. int end, {
  3. int step = 1,
})

Returns integers from start (inclusive) toward end (exclusive) in increments of step. A negative step counts down; the result is empty when the range cannot advance toward end.

Example:

rangeInt(0, 5);            // [0, 1, 2, 3, 4]
rangeInt(5, 0, step: -2);  // [5, 3, 1]

Implementation

List<int> rangeInt(int start, int end, {int step = 1}) {
  final List<int> out = <int>[];
  for (int i = start; step > 0 ? i < end : i > end; i += step) {
    out.add(i);
  }
  return out;
}
