vertWarning method

void vertWarning(
  1. int _x,
  2. dynamic _y,
  3. dynamic count,
  4. String _s,
)

aBox calls warnings in case of over-length-width box in matrix. Set vertical Warning-line for over-sized-box to screen matrix

Implementation

void vertWarning(int _x, _y, count, String _s) {
  String _newS;
  int toX = 0;
  //  howTo NULL   cast it to int.. yes, WORKS
  toX = (_x + count).toInt();

  for (var x = _x; x < toX; x++) {
    _newS = tl.changeLetter(_matrix[x], _y, _s);
    _matrix[x] = _newS;
  }
}
