Heat Map in compose

[majatestad]

I'm searching for functionality to implement heat map over my map in jetpack compose. I have not found any documentation on this, and as I understood from my Discourse request, there may not be any solution for this yet.

Heatmaps are working just fine as it is. You need to use TileOverlay together with HeatmapTileProvider. See: https://developers.google.com/maps/documentation/android-sdk/utility/heatmap

IIUC, you will have to use a MapEffect to add a heat map to a composable map.

If you follow this [example] (https://developers.google.com/maps/documentation/android-sdk/utility/heatmap#simple), you would just need to change this call val overlay = map.addTileOverlay(TileOverlayOptions().tileProvider(provider)) to happen in a MapEffect.

This particular part should be similar to how other layers are added to the composable map. See this example https://developers.google.com/codelabs/maps-platform/maps-platform-101-compose#outline-the-mountain-ranges
