removeRange method

void removeRange (int start, int end)
override

Removes the objects in the range start inclusive to end exclusive.

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.

Throws an UnsupportedError if this is a fixed-length list. In that case the list is not modified.

Implementation 

void removeRange(int start, int end) {
  RangeError.checkValidRange(start, end, this.length);
  if (end > start) {
    _closeGap(start, end);
  }
}
