Hi everyone facing this issue, This issue seems to have been fixed on version 2.0.0 of the plugin onward as mentioned at https://github.com/googleads/googleads-mobile-flutter/issues/594#issuecomment-1196970456. So, please try use the latest version and check if the issue still reproduces.

Just had this issue today while using

google_mobile_ads: ^3.0.0. firebase_core: ^2.15.0 firebase_analytics: ^10.4.4

Couldn’t get it to work at all until I changed to google_mobile_ads: ^2.4.0 in my subspec.yaml file. Then I ran

flutter pub get pod repo update pod install flutter build iOS flutter run

Now all is good. Mac M2 chip. Hope this helps someone.

Yay, this is fixed in google_mobile_ads: ^2.2.0

I also can reproduce this issue with firebase_analytics: ^10.0.2 and google_mobile_ads: ^2.1.0.

Same error for RewardedAd.load too, even if I use @jslattery26 fork:

Ref code for loading Reward ad:

        request: const AdRequest(),
        rewardedAdLoadCallback: RewardedAdLoadCallback(

            print('$ad loaded.');
            // Keep a reference to the ad so you can show it later.
            reward = ad;
            reward!.fullScreenContentCallback = FullScreenContentCallback(
              onAdShowedFullScreenContent: (RewardedAd ad) =>
                  print('$ad onAdShowedFullScreenContent.'),

                print('$ad onAdDismissedFullScreenContent.');
                ad.dispose();
                reward = null;
              },
              onAdFailedToShowFullScreenContent:
                  (RewardedAd ad, AdError error) {

                ad.dispose();

              },

            );

            //Fire away
            reward!.show(
