A modern programming language that makes developers happier.

I'd love to know if anyone has explored the _Unidirectional Data Flow_ for Android? I took a unique approach implementing it with *LiveData* + *Kotlin* as opposed to *RxJava*. A few major *Kotlin* benefits with this pattern are the `Sealed class` and the shallow `.copy(..)` function.

I'd love any feedback on this new approach! :slightly_smiling_face: :robot_face:

Undirectional Data Flow It's a great approach, but it's going to be better when `Compose` gets released and actually I'm using coroutines (`Flow` extension) to implement a kind of Redux implementation <https://gist.github.com/bloderxd/830e92702b92c4cf0906c57e54726e14>

but it's a good approach, I'm just pretty excited about compose to use better

There is no need to wait for Compose to try Declarative UI on Android, it is already there

how do u try that without Compose? Let's suppose you have this:

```
fun render(state: MyState) {
 
}
```

this `MyState` is the view state, how do u render that today properly with no imperative way? :thinking_face:

of course u can build tools for that, but just with android framework, how do u do?

Different ways. You can use declarative UI libraries like Litho, Anko, Anvil which allows exactly this.
But if you still prefer plain old xml for some reason, you can mimic this render() method by your own.

Yeah I can create tools for that but I'm waiting some kind of official support to that.

My point is that you don't even need to create one, they are already there. But yes, they are not "official"

Hey <@U4TNC7C4B>, <@U1S5XNVK8>,  I am just seeing these messages now. I switched from Slack web to the app so that I'll receive  realtime notifications moving forward! :mailbox_with_mail:

<@U4TNC7C4B>, Thank you for the feedback! I haven't explored `Compose` yet. I've started using *Coroutines* to handle basic threading use cases, but need to look into the `Flow` extension. Your code sample is interesting!
