Hi, I am looking for way to add screen trace log for firebase performance metric to compose screens (similar to slow rendering/frozen frames metric of activity and fragment). Any idea where we should start and stop the trace?

Not sure if it is the best way but you can start the trace on every successful composition:

@Composable
inline fun TraceCompositions() {
        SideEffect { Trace.beginSection() }
}

And stop the trace within a DisposableEffect, something like:

@Composable
inline fun TraceCompositions() {
        SideEffect { Trace.beginSection() }
 DisposableEffect() {

        onDispose {
        Trace.endSection()
        }
    }
}
