Multiple random numbers in dart

I would like to ask what is the best way to generate five UNIQUE random numbers (0-99).

I'm only familiar with generating a random number like this:

var randomizer = Random();

var num = randomizer.nextInt(100);
print(num);

Is there a way how to easily generate 5 different random numbers?

I think the simplest way to get five unique numbers from 100 is:

void main() {
  var list = List<int>.generate(100, (i) => i)..shuffle();
  list = list.take(5).toList();
  print(list);
}

we generate list with elements, then shuffle it and take first five elements

If you meant to generate list of 5 random numbers.

You can

var randomizer = new Random();
var l = List.generate(5, (_) => randomizer.nextInt(100));
