Intergrating both synchronous and asynchronous libraries

Can synchronous and asynchronous functions be integrated into one call/interface whilst maintaining static typing? If possible, can it remain neutral with inheritance, i.e. not wrapping sync methods in async or vice versa (though this might be the best way).

I've been reading around and see it's generally recommending to keep these separate (http://www.tagwith.com/question_61011_pattern-for-writing-synchronous-and-asynchronous-methods-in-libraries-and-keepin and Maintain both synchronous and asynchronous implementations). However, the reason I want to do this is I'm creating a behaviour tree framework for Dart language and am finding it hard to mix both sync and async 'nodes' together to iterate through. It seems these might need to be kept separate, meaning nodes that would suit a sync approach would have to be async, or the opposite, if they are to be within the same 'tree'.

I'm looking for a solution particularly for Dart lang, although I know this is firmly in the territory of general programming concepts. I'm open to this not being able to be achieved, but worth a shot.

Thank you for reading.

You can of course use sync and async functions together. What you can't do is go back to sync execution after a call of an async function.

Maintaining both sync and async methods is in my opinion mostly a waste of time. Sometimes sync versions are convenient to not to have to invoke an async call for some simple operation but in general Dart async is an integral part of Dart. If you want to use Dart you have to get used to it. With the new async/await feature you can write code that uses async functions almost the same as when only sync functions are used.
