this ad may have not been loaded or has been disposed. native ads

Trying to implement Native ads but it showing this error… “this ad may have not been loaded or has been disposed. Ad with the following id could not be found: 1 /6”

Java Code of android…

public class MainActivity extends FlutterActivity {
    @Override
    public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        super.configureFlutterEngine(flutterEngine);
        final NativeAdFactory factory = new NativeAdFactoryExample(getLayoutInflater());
        GoogleMobileAdsPlugin.registerNativeAdFactory(flutterEngine, "adFactoryExample", factory);
        GoogleMobileAdsPlugin.registerNativeAdFactory(flutterEngine, "listTile",
                new ListTileNativeAdFactory(getContext()));
    }

    @Override
    public void cleanUpFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        super.cleanUpFlutterEngine(flutterEngine);
        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "adFactoryExample");
        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "listTile");
    }
}

Do i need both listTile and adFactoryExample for Displaying Native and InlineNative?

Although i am not showing in same Page…

in HomePage showing with adFactoryExample…

  NativeAd _nativeAd;
  bool _nativeAdIsLoaded = false;

  @override
  void initState() {
    super.initState();

    _createInterstitialAd(); 

    _nativeAd = NativeAd(
      adUnitId: 'ca-app-pub-3940256099942544/2247696110',
      request: AdRequest(),
      factoryId: 'adFactoryExample',
      listener: NativeAdListener(
        onAdLoaded: (Ad ad) {
          print('natty $NativeAd loaded.');
          setState(() {
            _nativeAdIsLoaded = true;
          });
        },
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          print('natty $NativeAd failedToLoad: $error');
          ad.dispose();
        },
      ),
    );
    _nativeAd.load();
  }

  Widget nAdWidget() {
    final AdWidget adWidget = AdWidget(ad: _nativeAd);
    return Builder(
      builder: (context) => Container(
        child: adWidget,
        width: 250,
        height: 350,
        alignment: Alignment.center,
      ),
    );
  }

>>Scaffold
(
Container(.....),
...
nAdWidget(),
....,
Widget(....),
)

@override
  void dispose() {

    _interstitialAd?.dispose();

    _nativeAd?.dispose(); 

    super.dispose();

  }

another page… Using inline native… same error…

No issues in Flutter doctor…

I have the same error @viniciusddrft viniciusddrft
Can you help me fix this out?

PlatformException(NativeAdError, Can't find NativeAdFactory with id: adFactoryExample, null, null) I’m using Getx and this is my codes:

controller;

class NativeAdsController extends GetxController {
  late NativeAd myNativeAds;
  late AdWidget adWidget;

  final _loading = 0.obs;
  set loading(value) => this._loading.value = value;
  get loading => this._loading.value;

  NativeAdsController() {
    this.loadNativeAds();
  }

  get nativeAd {
    return this.myNativeAds;
  }

  get nativeAdWidget {
    return this.adWidget;
  }

  onClose() {
    this.disposeNativeAds();
  }

  loadNativeAds() async {
    myNativeAds = NativeAd(
      adUnitId: AdsHelper.getNativeAdUnitId(),
      factoryId: 'adFactoryExample',
      request: AdRequest(),
      listener: NativeAdListener(),
    );

    try {
      // this.disposeNativeAds();
      await myNativeAds.load();

      adWidget = AdWidget(ad: myNativeAds);

      this.loading++;
    } catch (err) {
      print('error load NativeAd ${err.toString()}');
    }
  }

  disposeNativeAds() {
    // adWidget.dispose();
    myNativeAds.dispose();
  }
}

widget;

class NativeAds extends StatelessWidget with WidgetThemes {
  NativeAdsController controller = Get.put(NativeAdsController());

  @override
  Widget build(BuildContext context) {
    initWidgetThemes(context);

    return Obx(
      () => ((controller.loading > 0) && (null != controller.nativeAd))
          ? Container(
              color: Colors.amber,
              alignment: Alignment.center,
              child: controller.nativeAdWidget,
              width: 200,
              height: 200,
            )
          : SizedBox.shrink(),
    );
  }
}

Setups in Android are:

    @Override
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        GoogleMobileAdsPlugin.registerNativeAdFactory(flutterEngine, "adFactoryExample", NativeAdFactoryExample( LayoutInflater.from(context)))
    }

    @Override
    override fun cleanUpFlutterEngine(flutterEngine: FlutterEngine) {
        super.cleanUpFlutterEngine(flutterEngine)
        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "adFactoryExample")
    }
}

class NativeAdFactoryExample(val layoutInflater: LayoutInflater) : NativeAdFactory {
    override fun createNativeAd(
        nativeAd: NativeAd, 
        customOptions: Map<String, Any>?
        ): NativeAdView  {
            val adView = layoutInflater.inflate(R.layout.my_native_ad, null) as NativeAdView 
            val headlineView = adView.findViewById<TextView>(R.id.ad_headline)
            val bodyView = adView.findViewById<TextView>(R.id.ad_body)
            headlineView.text = nativeAd.headline
            bodyView.text = nativeAd.body
            adView.setBackgroundColor(Color.BLUE)
            adView.setNativeAd(nativeAd)
            adView.bodyView = bodyView
            adView.headlineView = headlineView
        return adView
    }
}```
