Feature Request: Aggregating properties for clustered features

Late last year, Mapbox implemented clusterProperties attribute for ShapeSource, which enables declaring custom aggregated properties for clustered features on the map.

Android: https://github.com/mapbox/mapbox-gl-native/pull/15425 iOS: https://github.com/mapbox/mapbox-gl-native/pull/15515

I would very much like to see this implemented, as we have a use case in our app where we want to open a new view on cluster tap, which shows information for all features clustered under the icon. Additionally, we want to show information on the icon which is more complex than simple {point_count}.

I have started implementing it myself, and got it working on Android – but due to the outstanding use_frameworks! issue on iOS (https://github.com/mapbox/mapbox-gl-native-ios/issues/154), I haven’t been able to fully test this.

If anyone wants to take over the branch from https://github.com/ivari/maps/tree/implement-clustering-properties, you’re welcome to do so – otherwise I’ll come back to this at some future point and try to get a PR up.

Would love to see this implemented.

@ivari thanks it looks great, we’d need an example. BTW for use_frameworks! we now have a workaround: https://github.com/react-native-mapbox-gl/maps/pull/714
