QUESTION
I'm brushing up on my design patterns knowledge by going through them in Dart, and I'm currently working on the remote proxy pattern. As I understand, the pattern implies a shared interface between the real object residing on a server machine, and the proxy object on a client machine.
I've managed to get all the networking between the client and server working fine, and i've set up a simple RPC API with dart's HttpServer
and HttpClient
, but there's one thing that's bugging me. The methods on the proxy object must be asynchronous because of the networking involved, but the real object's methods aren't asynchronous. It would appear that this makes it impossible for them to share an interface, and thus functional consistency between the two classes isn't guaranteed by the type system.
Is there a way to implement some kind of a future version of a certain interface in dart? I don't mean something that returns Future
, but something where the methods of SomeInterface
are implemented asynchronously with Future
return types. What i'm looking for is something like:
