Method getLayer("puck") throws "Layer puck is not in style" #527

Open AlbertoNoris opened 2 weeks ago

AlbertoNoris commented 2 weeks ago

On iOS (haven't tested Android) when trying to get the position of the user with the provided code in the example

    // wait until the style is loaded
    await state?.style.isStyleLoaded();

    // get the user position from the layer that contains the puck (the blue dot)
    Layer? layer;
    if (Platform.isAndroid) {
      layer = await state?.style.getLayer("mapbox-location-indicator-layer");
    } else {
      layer = await state?.style.getLayer("puck");
    }

    final userLocation = (layer as LocationIndicatorLayer).location;
    return Position(userLocation![1]!, userLocation[0]!);

as soon as the map is created then this error is thrown:

PlatformException (PlatformException(StyleError(rawValue: "Layer puck is not in style"), null, null, null))

Before updating to 1.1.0 from a pre 1.0.0 version this issue wasn't there; trying to get the position slightly after the map creation doesn't yield the Exception.

@AlbertoNoris The location indicator layer is not added to the style until the first location update is reported by the platform, to avoid this error you can check if the layer exists in the style before trying to access it - styleLayerExists().
