# compose

I'm trying to convert an activity to compose and I'm having trouble with this helper function to complete a trip, specifically with displaying different error messages with snackbar. I previously just got a View with findViewById and passed that to snackbar, but it looks like I can't do that anymore with compose. I'm thinking I could just switch to using a toast, though its style doesn't really match the rest of the app.

        ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
    ) {
        Snackbar.make(
            composeView.rootView, "Location needs to be enabled to retrieve current location", Snackbar.LENGTH_SHORT
        ).show()
