Playing with dart async/await delayed

dart-futures.dart

void main() async {
  Stopwatch stopwatch = new Stopwatch()..start();

  var p1 = delay(Duration(seconds: 2));
  var p2 = delay(Duration(seconds: 4));

  await p1;
  await p2;

  print('Executed in ${stopwatch.elapsed}');
}

Future delay(duration) => Future.delayed(duration);
