Exercise: Practice using async and await

hint.txt

You can do it! 

main.dart

// Complete the addUpOverFives() function so that it sums all elements of a given list that are greater than 5.

int addUpOverFives(List<int> input) {
    return 
}

solution.dart

int addUpOverFives(List<int> input) {
    return input.where((i) => i > 5).fold<int>(0, (previous, current) => previous + current);
}

test.dart

List<int> a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89];

main() async {
  try {
    var result = addUpOverFives(a);

    if (result == 220) {
      _result(true);
    } else {
      _result(false, ['Not quite... try again!']);
    }
  } on UnimplementedError {
    _result(false, [
      'Test failed! Did you remove the addUpOverFives function?',
    ]);
  } catch (e) {
    _result(false, ['Tried to run solution, but received an exception: $e']);
  }
}
