maps: Exception in onDidFinishLoadingStyle Attempt to invoke virtual method 'void com.mapbox.mapboxsdk.location.LocationComponent.setLocationComponentEnabled(boolean)' on a null object reference

Describe the bug private vodid stateChanged() getting called before mLocationComponent is initiated on map load hence resulting in NullPointerException

To Reproduce

Example:

<MapboxGL.MapView
        ref={map}
        style={[styles.container, props.style]}
        compassEnabled={false}
        onRegionIsChanging={onRegionIsChanging}
        rotateEnabled={props.rotationEnabled && !props.disableInteractions}
        onRegionDidChange={onRegionChanged}
        regionDidChangeDebounceTime={10}
        pitchEnabled={false}
        scrollEnabled={!props.disableInteractions}
        zoomEnabled={!props.disableInteractions}
        onLayout={props.onLayout}
        onPress={onPress}
      >
        <MapboxGL.Camera
          ref={camera}
          maxZoomLevel={18}
          defaultSettings={mapSettings}
          followUserLocation={props.keepUserCentered}
          followUserMode="normal"
        />
        {props.children}
        {/*
        //@ts-ignore*/}
        {props.showUserLocation && <MapboxGL.UserLocation showsUserHeadingIndicator renderMode="native" />}
      </MapboxGL.MapView>

Versions:

• Platform: Android
• Emulator/ Simulator: no
• OS: Android 8
• react-native-mapbox-gl 8.1.0-beta
• React Native Version 61.2

Additional context seems to be fixed by simple early return:

private void stateChanged() {
        if (mLocationComponent == null) return;
