Implementation

@override
Uint8List dispatchRect(Uint8List data, int width, int height, Rect rect) {
  final newByte = Uint8List.fromList(data);
  final random = math.Random();
  final rand = random.nextInt(4) + 3;
  for (int startH = rect.top; startH < rect.bottom; startH++) {
    for (int startW = rect.left; startW < rect.right; startW++) {
      final index = startH * width + startW;
      newByte[index] = (newByte[index] * rand);
    }
  }
  return newByte;
}
