Hello guys! I was wondering what is the best wat to pass data into composition? Let's say in my MainActivity I call another activity and get some data in the onActivityResult, how do I go about passing this data into my composition tree? I was thinking I could have an activity view model with a LiveData and do observeAsState inside, but I don't know if that is the best way

yeah i think just a plain old MutableState would be how i’d do this, but might depend on use case

Oh wait, MutableState is not compose specific? I can just have one in my activity and update it wheneve I want to trigger recomposition?

Thanks I was totally missing that part

We've talked about Activity Results a couple of times in the past - tracks making it easy to use the Activity Result API from Compose (but links to the code you can use right now)
