looping an if statement in a setstate – Flutter

I have a random dice generator with 2 dice. I’m using a compare statement to check the random result of the two dice and re roll if they are the same. here is the code to roll one of the dice

void Roll1() {
    setState(() {
      oneDiceNumber = Random().nextInt(6) + 1;
  if (oneDiceNumber == twoDiceNumber) {
        oneDiceNumber = Random().nextInt(6) + 1;
        twoDiceNumber = Random().nextInt(6) + 1;
      }
    });
  }

what I want the code to do is loop the if statement until it gets a result that isn’t a tie.

thanks so much

    Try a while loop

    oneDiceNumber = 0;
twoDiceNumber = 0;

while(oneDiceNumber == twoDiceNumber){
   oneDiceNumber = Random().nextInt(6) + 1;
    twoDiceNumber = Random().nextInt(6) + 1;
}

    You could also do this using recursion:
    Define a function called getRandomDice():

    getRandomDice() {
   int oneDiceNumber = Random().nextInt(6) + 1;
   int twoDiceNumber = Random().nextInt(6) + 1;
   if (oneDiceNumber == twoDiceNumber) {
       return getRandomDice();
   } else {
       return [oneDiceNumber, twoDiceNumber];
   }
}

    and you could call this using in your function like this:

    List<int> values = getRandomDice();
int firstNum = values[0];
int secondNum = values[1];
