Puck layer not added the same way on iOS and Android

When you set the puck settings as:

    mapboxMap?.location.updateSettings(
      LocationComponentSettings(
        pulsingEnabled: false,
        showAccuracyRing: true,
        puckBearing: PuckBearing.COURSE,
        puckBearingEnabled: true,
      ),
    );

You can access the puck layer with:

if (Platform.isAndroid) {
      puckLayerId = 'mapbox-location-indicator-layer';
    } else {
      puckLayerId = 'puck';
    }

    try {
      bool? puckLayerExists =
          await mapboxMap?.style.styleLayerExists(puckLayerId);

However when you use the same code for Android, it fails. The error tells you the puck layer does not exist.

In order to fix this you need to add enabled: true

    mapboxMap?.location.updateSettings(
      LocationComponentSettings(
        enabled: true, // Needed for Android
        pulsingEnabled: false,
        showAccuracyRing: true,
        puckBearing: PuckBearing.COURSE,
        puckBearingEnabled: true,
      ),
    );

I think this behavior should be consistent across iOS and Android. So I guess the bug is that when enabled: true is not provided on iOS it still adds the puck layer.

从 LocationComponentSettings.updateSettings 和 issue 中显示的 styleLayerExists 调用开始，然后比较 Flutter wrapper 在 iOS 和 Android 上如何配置 location component。确认省略 enabled 是否应当在两个平台上产生相同的 puck layer 行为；当行为一致且报告的 layer lookup 不再因平台而异时，即表示完成。
