SynchronousFuture<T> class
A Future whose then implementation calls the callback immediately.
This is similar to Future.value, except that the value is available in the same event-loop iteration.
⚠ This class is useful in cases where you want to expose a single API, where you normally want to have everything execute synchronously, but where on rare occasions you want the ability to switch to an asynchronous model. In general use of this class should be avoided as it is very difficult to debug such bimodal behavior.
A SynchronousFuture will never complete with an error.
