| * @assertion Let f be an asynchronous non-generator function with declared |

| * function futureValueType is defined as follows: |
| * |
| * futureValueType(S?) = futureValueType(S), for all S. |
| * futureValueType(S*) = futureValueType(S), for all S. |
| * futureValueType(Future<S>) = S, for all S. |
| * futureValueType(FutureOr<S>) = S, for all S. |
| * futureValueType(void) = void. |
| * futureValueType(dynamic) = dynamic. |
| * Otherwise, for all S, futureValueType(S) = Object?. |
