Can't change the default clusterItemContent (java.lang.IllegalStateException: Invalid applier)

[Youssef3ssamProgressio]

I am facing an Invalid applier error while using Jetpack Compose in conjunction with Google Maps clustering for custom markers.

---

Dependencies

implementation("com.google.maps.android:maps-compose:2.15.0")
implementation("com.google.maps.android:maps-compose-utils:2.15.0")

---

Steps to reproduce

1. Use Jetpack Compose with Google Maps clustering.
2. Add the following sample at MapClusteringActivity

// Optional: Custom rendering for non-clustered items
            clusterItemContent = {
                Marker(
                    state = MarkerState(position = it.itemPosition),
                    title = "Title",
                    snippet = "Snippet"
                )
            }

---

Expected Behavior:

I expect the Google Maps clustering to properly display the custom markers using Jetpack Compose, without facing any errors related to invalid appliers.

---

Code example

@OptIn(MapsComposeExperimentalApi::class)
@Composable
private fun ShowStations(stations: List<Station>) {
    Clustering(
        items = stations,
        onClusterClick = { true },
        onClusterItemClick = { true },
        onClusterItemInfoWindowClick = { },
        clusterContent = null,
        clusterItemContent = {
            Marker(
                state = rememberMarkerState(position = it.position),
                icon = bitmapDescriptor(LocalContext.current, R.drawable.ic_map_marker_default)
            )
        }
    )
}

me too, cannot add Marker in clusterItemContent, currently proceed with image as Marker, and then drop performance in Image Markers count with 1800+ , a little latency in pinch and zoom.

[cwsiteplan]

the cluster content lambda cannot take a Marker composable, but expects just a plain composable. (no handling of marker state) this however has major drawbacks as you cannot configure properties of the Marker (like anchor or zIndex) when using a cluster.

[cwsiteplan]

update: latest release does add zIndex handling to clusters.

[tcoxMonkeyCoder]

@cwsiteplan How are you applying a zIndex to the cluster items? I'm on 4.3.0 and I see no such property on the Clustering Composable, and I run into the original Invalid applier issue if I try to use a Marker with a zIndex.

[cwsiteplan]

do you mean version 4.3.0 ? (latest) or really 3.4.0 - which is quite old an does not have the capability.

the com.google.maps.android.clustering.ClusterItem now has getZIndex() which can be override by your cluster item

[tcoxMonkeyCoder]

@cwsiteplan Sorry for the typo, yes I'm on 4.3.0 and getZIndex() solved my problem. I guess I was assuming it would be a parameter on the composable for some reason, but makes sense to be on the item. Thank you!

[feivur]

facing this issue too

[Lizzergas]

This probably won't get fixed or will it?

Would be nice to get a proper solution, instead of applying Projected content as a InfoWindowContent, since I really wanted to use MarkerInfoWindowContent
