How to finish with result and examine result in a parent

[dimsuz]

What is the idiomatic way to finish with result? For example:

• AppFlow starts LoginFlow
• LoginFlow can end with "Dismissed", "Success", "AdditionalIdentificationRequired" statuses
• AppFlow should be able to somehow receive these outcomes and decide where to route next

If I'd express this with lambdas it could be something like:

appFlow {
   val result = loginFlow()
   when (result) {
     is Dismissed -> Unit
     is Success -> mainFlow()
     is AdditionalIdentificationRequired -> identifyFlow(result.idLevel)
}

Hi @dimsuz, thanks for your question.

You should use childAware API to establish connection between parent and a child. Then it's up to you how you communicate between the parent and the child.

You could use simple callbacks or provided by library reactive solutions com.bumble.appyx.interop.rx2.connectable.NodeConnector.

Thanks! Is there analog of NodeConnector for kotlin's coroutines Flow? Didn't find it in libraries folder. Not sure I need it, and perhaps it would be hard to write it, just curious if I missed something.

Unfortunately, at the moment we don't have an analogue for coroutines

I've created a coroutines variant of Appyx's NodeConnector. Open to feedbacks :)
