A modern programming language that makes developers happier.

kotlinlang

is it more idiomatic/preferred to expose a `mutableStateOf` or a `StateFlow` /  `LiveData` property from a ViewModel?

I would prefer Flow, since it’s available on all platforms and doesn’t rely on any libraries that aren’t in the standard library.

I think mutableStateOf is idiomatic. Definitely not livedata if you can avoid it

I noticed this <https://developer.android.com/jetpack/compose/state#viewmodels-source-of-truth>, but it feels like we are putting view implementation/related API's inside the ViewModel if we use `mutableStateOf`

If you use Flow, you can create your state in compose using `val state by fooFlow.collectAsState(defaultFoo)`  to avoid having to put `state.value`  everywhere. You can just use the state variable directly, which I find idiomatic enough. Bonus points for using a data class for state and having your state for the screen all come from a single flow.

Most of the implementation here exposes flows from the viewmodel and not a `mutableStateOf` property <https://github.com/android/nowinandroid>
