Hello everyone! I am trying to find some useful resources about how to handle “events” in Compose Multiplatform. I am currently developing app for android/ios using moko for ViewModels and Voyager for navigation. I am especially interested if there are some examples of how to handle events that originate from ViewModel. So for example:
• user presses a button -> function in VM is called to save something to db -> depending on the result fail/success you either show an error or trigger navigation via event.

dont use moko use precompose viewModel its way simpler and better also they precompose koin fo DI, you can also use precompose for navigation

[Mark Frelih]

Do you have any example how event triggered from ViewModel is handled?

I think you are talking about an old MVVM problem. If it is what I think is not related to Moko or Voyager but a general View and VM interaction. Long story short, represent your events as state if you want 100% delivery/consumption guaranteed

There's a good article from Manuel Vivo talking about that

[Mark Frelih]

Correct! It is nothing directly connected to the libraries. I am just trying to hear people’s opinions and see some examples.

Yeah here is the article I think you are talking about: https://medium.com/androiddevelopers/viewmodel-one-off-event-antipatterns-16a1da869b95
But there is a lot of discussion going on whether this is the right way or not. Here is an article that does not agree with using events as a state: https://proandroiddev.com/viewmodel-events-as-state-are-an-antipattern-35ff4fbc6fb6
