This code snippet might help:

// generate a list of 0 to 100 (inclusive) as Strings
final numbers = List.generate(101, (index) => index.toString());

// shuffle those
numbers.shuffle();

// print each of them, just as an example here
numbers.forEach((number) => print(number));

// or take the last one each time
final number = numbers.removeLast();
