Change filter of base style layer

[jvojacek]

Hello,

Thank you very much for your work - providing a variant of Compose MapLibre. It works well, but I have a question for you.
In my application I need to change filter of layer, which is defined in the base map style .json, to show different data. I found some discussions/issues on this topic, but I don't understand much. You said something about Anchor.replace(), but I don't know how to do it.. can you please provide some code to change the filter?
Is that even possible? Also, is it possible to read other properties of the base layer?
Thank you for the answer.

Regards,
Jakub

What you want is #18, which isn't implemented yet.

Anchor.Replace is one workaround that allows you to replace a layer from the base style. So you'd write something like this and configure that new layer following these docs.

Anchor.Replace("some-base-layer-id") {
  LineLayer(...) // or any other kind of layer
}

The other workaround is to get the map style as a JSON string and edit it before passing it to the map.
