Implementation

void numGenerator() {
  //generates the numbers to display on screen
  int nextNum =
      _random.nextInt(widget.activity.interval) + 1; //plus one to not get 0.
  while (newNum == nextNum) {
    //currently code enforces no repetition of numbers - for graphical sakes.
    nextNum = _random.nextInt(widget.activity.interval) + 1;
  }
  newNum = nextNum;
  curSeq.add(newNum);
