What is a future? (completed)

main.dart

Future<void> fetchUserOrder() {
  // Imagine that this function is fetching user info from another service or database
  return Future.delayed(Duration(seconds: 3), () => print('Large Latte'));
}

void main() {
  fetchUserOrder();
  print('Fetching user order...');
}

Comment in line 2 says user info, but code in line 3 is about user order.
