Set Map Layers dynamically

[maxammann]

Is your feature request related to a problem? Please describe. The clusters on the map are right now bavaria blue. We might want to set the particular theme color. Currently the layers are hardcoded in the styles.json and should set dynamically to set the cluster color depending on the projects build configuration (theme color)

Describe the solution you'd like

• create dynamic layers in flutter (as we do in react-native)
• set the particular theme color for the cluster layer
• set the icon directly for each poi by just setting the category in the symbol layer. We may consider categoryId and projectId
• ensure legacy support (maintain styles.json)

Describe alternatives you've considered None

Additional context Current hardcoded layer solution styles.json (https://github.com/digitalfabrik/ehrenamtskarte-maplibre-style/blob/22cc66f0a9a361372496fe2f2d29d4fb0ee70fdf/style.json#L1597) Here are some infos how to do it https://github.com/maplibre/flutter-maplibre-gl/blob/6eb27181f2ecfc34a883c74ef681e61f8e3f2fb3/example/lib/layer.dart#L228 This would also enable to customize the cluster colors per project. Additionally we could just pass the categoryId or favoriteIcon as icon-image as we do for integreat

Is there currently a way to pass arguments to the map styles from within the app? Or would this be done by using env variables?

[maxammann]

Hm, I think there are already different styles for the map. One for entitlementcard and one for ehrenamtskarte. If not we can do that I think.

They get deployed and we just have to change the url in the build config.

so we'd need a repo for the nuernberg map-libre-styles? Not sure how to handle this with the git submodules here ^^ I was rather thinking about passing a style to the map (or selecting one) as this one is just about changing the color of the clusters.

hm not sure how this works here in flutter but you maybe could also provide these cluster layers in the app instead of the style.json as we do in integreat @sarahsporck . That would it make easy to pass the theme colors we want. I think to have fore each new whitelabel project a separate map-libre style repo looks very complicated to me

[sarahsporck]

I agree with you.And this should be fairly easy by just adding some functioanality to the MapStyleHandler.

@sarahsporck i just checked out how to accomplish this and updated the issue with further information and moved it to "NextUp"
