is there a way to handle life cycle as we are not using fragment and only one activity is there is project, i need inform view model 1. when compose screen created 2. when app go in background 3. when moving from one screen to another and when we are coming back to same screen 4. basically all lifecycle event

Have a look at this post that explains the new lifecycle api: https://medium.com/androiddevelopers/a-safer-way-to-collect-flows-from-android-uis-23080b1f8bda

Just do it in the activity and pass the values to the viewmodel, which then in turn can expose StateFlows to inform your composition

in my project there are around 15-20 module it will be difficult to handle everything in one activity a

Yes, you have the

repeatOnLifecycle

that’s explained in the linked post above. They even have an example with Compose at the end

Lifecycle events are still a thing in Compose: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1630080009198100?thread_ts=1630078038.194200&cid=CJLTWPH7S

I am wondering how the lifecycle handling concepts explained in the article will map to Compose Desktop where you are facing the same problem but don’t have all these Android specific APIs available. Or am I missing something here?
