# Writing a 'for loop' for random no which is not zero(0) but still I'm getting zero(0)

### Question Asked by abhijeet on November 23, 2021 (source).

I'm new to dart, and I'm writing the following for loop for random num which is not a zero, but it still returns zero to me:

``````  int Num = 1;
for (var i = 1; i != 0 && i <= 6; i++) {
final _random = Random();
Num = _random.nextInt(i);
}
print('Randon num is \$Num');
``````

A good place for problems like this is the dart api. This link provides you with everything you need.

Here it says the following:

nextInt(int max) → int Generates a non-negative random integer uniformly distributed in the range from 0, inclusive, to max, exclusive. [...] Also i represents the max value the nextInt() method will produce.

To generate a single random number:

``````import 'dart:math';

void main() {
int maxNb = 10;

generateRandomNumber(int maxNb) {
final int number = Random().nextInt(maxNb) + 1;
return number;
}

int result = generateRandomNumber(maxNb);
print(result);
}
``````

To generate multiple random numbers:

``````import 'dart:math';

void main() {
int maxNb = 10;
int amount = 6;
List randomNumbers = [];

generateRandomNumbers(int amount, int maxNb) {
for (var i = 1; i <= amount; i++) {
final number = Random().nextInt(maxNb) + 1;
