CircleStyleLayer and the filter property

[ynibling]

Hello,

I'm not sure if this is a bug or a future feature.
I saw in the API documentation that there is a way to apply a style to specific elements contained in the source, which in my case is a geojon source.

For example, in the CircleStyleLayer class (https://pub.dev/documentation/maplibre/latest/maplibre/CircleStyleLayer-class.html), there is a property called “filter.” In the Flutter package, the CircleStyleLayer constructor does not call super.filter, so my IDE obviously detects a problem with the filter property when I try to add it.

Am I missing something to make the filter work? Or is this a feature planned for a future release?

Thank you for your help and for this great package!

Hello @ynibling,
thanks for bringing it to attention. It's part of the StyleLayer interface but wasn't part of the MVP therefore not implemented yet. It's definetely planned for a future release.

Hello @josxha,

Thank you for your prompt reply and thank you for planning to implement this in a future version!

Hello,

I saw that in the last release the filter properties had been implemented. Thank you for that!
I gave it a try, but I couldn't get a filter to work. For exemple I tried this:

      const circleLayerWaypoint = CircleStyleLayer(
      id: 'itinerary_waypoint_circle', 
      sourceId: _geojsonSourceId,
      filter: [
          '==',
          [
            'get',
            'type'
          ],
          'waypoint'
      ],
      paint: {....}

Is it the right syntax? If not, can you give me an example of a filter?
Thank

I found a parsing bug on android. Can you check if #453 solves the problem for you?

Sorry, I'll be away all next week, I'll check it when I get back.

No problem, thanks for the info. I'll release the fixes now and if there is still an unsolved issue, I can take another look. 👍

I upgraded to maplibre 0.3.3+2 and the filtre property works just fine! Thank you

Glad it works now. Thanks for the feedback.
