Examples of using Arrow-Fx arrow on Android https://github.com/LordRaydenMK/Android-Fx-Examples inspired by this repo about Coroutines on Android -> https://github.com/LukasLechnerDev/Kotlin-Coroutine-Use-Cases-on-Android

It's still a WIP, some of the examples lack descriptions but I wanted to share..... any feedback is welcomed

I’m learning about ViewModel, I’ve been away for a while

[pakoito]

is it recommended to kickstart business logic in the constructor, or can it be deferred to onCreate or another time?

[pakoito]

the examples themselves are beautiful Stojan 😄

effectMap is precisely this pattern 😄

[stojan]

I would not say it's the recommended way... But easiest way to guarantee it's kicked off only the first time the screen is opened and not on rotation

[stojan]

Isn't that flatTap now?

[raulraja]

this is great Stojan, please don’t forget to contribute it to the blog 😍

[pakoito]

flatTap is apply IO and ignore result. effectMap is map a suspend function

[stojan]

@raulraja thanks... I will add it to the Projects and examples section

[stojan]

@pakoito _viewState.postValue(it) is not really suspended 🙈

[stojan]

but one would wrap LiveData updates in suspended functions

[pakoito]

it’s side-effecty, it could be considered 😛
