Immutable Collection prevent composition many times even if required

[ankitk77]

I need to draw polylines if I pass List<LatLng> it's fine but recomposing unnecessarily

if I pass `ImmutableList` it's skipping composition even if required many times

Update : Even if we mark data class with @Stable then also many times it skips composition

Update 2: got some workaround wrapping the compose method with key block and providing the list as key seems to work when using ImmutableCollection

data class Polyline(val latLngs : ImmutableList<LatLng>)
val mapPolylineList = persistentListOf<Polyline>()
key(mapPolylineList) {
    PlotPolyline(mapPolyline = mapPolylineList)
}

Any explanation on how this works ??

@GaneshShetty951 it's does exactly same how having parms in composable works but for some reasons composable annotated with @GoogeMapsCompose was not behaving correctly so key block also does the same if value changes then only it will recompose it's block

Exact same behavior with Marker. Using ImmutableCollection does not trigger a recomposition of Marker which causes some markers to not appear
