Try using a `for in` loop.

main.dart

List<int> _doubler(List<int> nums) {
  // your code here
}

solution.dart

List<int> _doubler(List<int> nums) {
  for (var n in nums) {
    n = n*2;
  }

  return nums;
}

test.dart

var nums = [1, 2, 3];

void main() {
  final _doubled = _doubler(nums);
  for (var item in _doubled) {
    if (_doubled.contains(item)) {
      continue;
    } else {
      _result(false, ["The solution should include [2,4,6]"]);
    }
  }
  _result(true, ["Good work, fam"]);
}
