1. Random? random

])
override

Shuffles the elements of this list randomly.

    final numbers = <int>[1, 2, 3, 4, 5];
    numbers.shuffle();
    print(numbers); // [1, 3, 4, 5, 2] OR some other random result.

## Implementation

    void shuffle([Random? random]) {
      random ??= Random();

      int length = this.length;
      while (length > 1) {
        int pos = random.nextInt(length);
        length -= 1;
        var tmp = this[length];
        this[length] = this[pos];
        this[pos] = tmp;
      }
    }
