I have MyScreen Composable function. I want to load some data from server when this screen appears. In usual android I would use

onResume()

and what I supposed to do now.

Probably

LaunchedTask

would be best, since it launches a coroutine that will automatically get cancelled when the function leaves the composition. If your API is callback based, you could also use

onActive

or

onCommit

with

onDispose

(soon to be renamed to

DisposableEffect

).

Hey. But, i cannot use composable functions inside it, isn't?

I've been updating a state from callback from

LaunchedTask

-> https://github.com/jeremyrempel/yahnapp/blob/8d12347c60b6566a1da1af2b9a3051a87eccc2b4/app/src/main/java/com/github/jeremyrempel/yanhnapp/ui/screens/CommentsScreen.kt#L77-L81 . I'm not sure if there is a better way

Correct, you cannot call composable functions from “effect” functions (like

onCommit

,

*Effect

)
