解决办法：

• 解决前状态如下:

    /** Init */
    init {
        //Method call handler
        methodChannel.setMethodCallHandler(this);
    }

    /** Platform view */
    override fun getView(): View {
        mMapView.let {
            mMapView.onCreate(null);
            mMapView.onResume();
            mMapView.map.uiSettings.apply {
                isCompassEnabled = true;
            }
            mMapView.map.setOnMarkerClickListener(this)
            mInfoWindowAdapter.setOnConfirmListener(this);
            mMapView.map.setInfoWindowAdapter(mInfoWindowAdapter);
        }
        return mMapView;
    }
