The layer '8PV9AZ2VbO_0' uses more data-driven properties than some devices may support. Though it will render correctly on this device, it may have rendering errors on other devices. To ensure compatibility with all devices, use 2 fewer data-driven properties in this layer.

I am trying to add symbols to the map using the lib. And this happened, please help.

What I did was:

• create list of marker data by using current viewport from getVisibleRegion() and generate random latlng in bound
• and create a class LocationPOI that has properties: name, type(enum), latlng
• clear current symbols using controller?.removeSymbols(controller?.symbols.toList() ?? [])
• and use addSymbols() to add list of poi to map

And this still happened, what could have gone wrong.

PS: testing on android pixel physical device is working with warning but with emulator it warns and the markers that are fetched from server is gone black color.

I haven't seen this warning before, but is it possible that your map style is quite complicated? Specifically uses many data expressions (see https://maplibre.org/maplibre-style-spec/expressions/#data-expressions for a definition of what are data expressions)?

First of all, thank you for replying to my issue. I very much appreciate it.

As for the map style, my team member who handled the vector map data said he didn't do much with the original 'omt-bright' style. So, I don't think the style file got much more complicated from the original file.

FYI: in flutter code, I use function controller.addSymbols() for marker and another controller.addSymbols() for the same dataset for rendering marker title text and await controller.setSymbolIconAllowOverlap(true); await controller.setSymbolIconIgnorePlacement(true); await controller.setSymbolTextAllowOverlap(false); await controller.setSymbolTextIgnorePlacement(false);
AND interestingly this only appear on android emulator, I'm not sure with other low-resource android devices but our testing physical device have no problem, both ios and android.
