This is the line it errors on

at io.flutter.plugins.googlemobileads.FlutterBannerAd.load(FlutterBannerAd.java:60)

on the following devices

Im am using google_mobile_ads google_mobile_ads: ^1.0.1

and Flutter 2.8.0

Edit:

This is our statefull widget

class MyBannerAd extends StatefulWidget {
  const MyBannerAd();

  @override
  _MyBannerAdState createState() => _MyBannerAdState();
}

class _MyBannerAdState extends State<MyBannerAd> {
  late AdSize adSize;
  late AdMobRepository adRepository;
  late AnalyticsRepository analyticsRepository;
  bool adLoaded = false;
  BannerAd? anchoredBanner;

  @override
  void initState() {
    super.initState();
    adRepository = context.read<AdMobRepository>();
    analyticsRepository = context.read<AnalyticsRepository>();

    if (SizerUtil.deviceType != DeviceType.mobile && SizerUtil.orientation == Orientation.portrait) {
      adSize = AdSize.leaderboard;
    } else {
      adSize = AdSize.largeBanner;
    }

    final bannerAd = adRepository.getBannerAd(
      size: adSize,
      onFailedLoad: (ad, error) {
        print('banner ad failed to load: $error');
        ad.dispose();
      },
      onLoad: (ad) {
        setState(() {
          adLoaded = true;
          anchoredBanner = ad as BannerAd?;
        });
      },
      onAdImpression: (_) {
        analyticsRepository.sendBannerAdShownEvent();
      },
      onAdOpened: (_) {
        analyticsRepository.sendBannerAdClickEvent();
      },
    );

    bannerAd.load();
  }

  @override
  void dispose() {
    super.dispose();
    anchoredBanner?.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return BlocBuilder<SubscriptionBloc, SubscriptionState>(
      builder: (context, state) {
        final isLoaded = !adLoaded;

        if (isLoaded || state.hasSubscribed || anchoredBanner == null) return SizedBox.shrink();

        return Container(
          color: Colors.transparent,
          width: anchoredBanner!.size.width.toDouble(),
          height: anchoredBanner!.size.height.toDouble(),
          child: Center(
            child: Container(

            ),
          ),
        );
      },
    );
  }
}

I fixed it ! For me the solution was to update app/build.gradle and explicitly this line :

classpath 'com.android.tools.build:gradle:4.1.1' to classpath 'com.android.tools.build:gradle:4.2.2'

Getting the same crashes with Flutter (Channel stable, 3.3.0) and google_mobile_ads 2.0.1

Tobias-Keller on Sep 20, 2022

@EArminjon I have tried to use Gradle 7.0.4 because it was the Gradle version used by new project in Android Studio Arctic Fox | 2020.3.1 Patch 4

If i create a new project in Android Studio Bumblebee | 2021.1.1 Patch 1 i can see the current Gradle version is 7.1.1 and i can find the lines i need to manually upgrade flutter project to current gradle version in build.gradle and gradle-wrapper.properties

Release notes: https://developer.android.com/studio/releases/gradle-plugin#7-1-0

To upgrade gradle to current version in flutter project

in android\build.gradle :

`buildscript {

dependencies {
    classpath 'com.android.tools.build:gradle:7.1.1'

}

in android\gradle\wrapper\gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-bin.zip

change in android\app\build.gradle

dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" }

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}

If i open the Android folder of the flutter project in Android Studio Bumblebee | 2021.1.1 Patch 1 it suggest to update the gradle plugin
