String middleCut(String text, int length){
  const numberOfDots = 3;
  final dotsString = List<String>.filled(numberOfDots, '.').join();
  
  
  int leftSizeLengh = ((length - numberOfDots) / 2).floor();
  int rightSizeLength = text.length - leftSizeLengh;
  return '${text.substring(0, leftSizeLengh)}$dotsString${text.substring(rightSizeLength)}';
