Question

I am using for navigation in Compose Multiplatform I have a google login button that should use `ActivityResultLauncher` to get the google account token and pass it to a callback in my ViewModel to authenticate From my understanding however `ActivityResultLaunchers` and their callbacks must be declared in Activity s `onCreate` before Compose s `setContent` At the same time though any ViewModels managed by Voyager must be created in a `Screen` as outlined in their which is called inside `setContent` similar to a Composable So my ViewModel callback must be present when the launcher is created before `setContent` but is also only available inside `setContent` using Voyager Is there a clean way around this

I ve also thought about just creating the ViewModel in the Activity but that also seems wrong

Are you using `rememberLauncherForActivityResult`

Activity Result APIs work directly in composables <https developer android com jetpack compose libraries activity result|https developer android com jetpack compose libraries activity result>

I forgot to mention I am specifically doing Google login in Compose Multiplatform For Android specifically there seems to be three components 1 `GoogleSignInClient` Must be created in an Activity provides sign in intent to 2 `ManagedActivityResultLauncher` Launcher for Google sign in activity 3 Sign in ViewModel function My custom authentication in using google account token launcher should provide Google account token to this function in launcher callback 2 can be available in Activity and Composables using `rememberLauncherForActivityResult` but 1 is only available in Android activity and 3 is only available in shared composables since that s where the Voyager `ScreenModels` are created The only solutions I can think of is a provide 1 to 3 but that would mean passing an Android dependency into my common Composables b provide 3 to 1 by creating my ViewModel in the Activity but that would go against Voyager s VM management inside Composables Not sure if there is a clean way around this
