[under3415]

Plugin Version

3.0.0

Steps to Reproduce

1. Run flutter create bug.
2. Update main.dart files as follows:

   
   import 'package:flutter/material.dart';
   import 'package:google_mobile_ads/google_mobile_ads.dart';

void main() { runApp(const MyApp()); }

class MyApp extends StatelessWidget { const MyApp({super.key});

// This widget is the root of your application. @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: const MyHomePage(title: 'Google Ads Demo'), ); } }

class MyHomePage extends StatefulWidget { const MyHomePage({super.key, required this.title});

final String title;

@override State createState() => _MyHomePageState(); }

class _MyHomePageState extends State { RewardedAd? _rewardedAd; bool _loadingAd = false;

Future _adBuyDialog() { return showGeneralDialog( context: context, barrierDismissible: false, transitionBuilder: (context, animation, secondaryAnimation, child) { return FadeTransition( opacity: animation, child: ScaleTransition( scale: animation, child: child, ), ); }, pageBuilder: (context, animation, secondaryAnimation) { return SafeArea( child: Scaffold( backgroundColor: Colors.amber, body: ElevatedButton( style: ElevatedButton.styleFrom( backgroundColor: Colors.green, elevation: 0, minimumSize: const Size( 150, 50, )), onPressed: () async { await showRewardedAd(); if (!mounted) { return; } Navigator.pop(context); }, child: const Padding( padding: EdgeInsets.all(8.0), child: Text( "Watch Ad", style: TextStyle(color: Colors.black, fontSize: 12), ), ), ), ), ); }, ); }

Future get _createRewardedAd async { _loadingAd = true; await RewardedAd.load( adUnitId: 'ca-app-pub-3940256099942544/5224354917', //sample ads request: const AdRequest(), rewardedAdLoadCallback: RewardedAdLoadCallback( onAdLoaded: (RewardedAd ad) { _rewardedAd = ad; _loadingAd = false; }, onAdFailedToLoad: (LoadAdError error) { _rewardedAd = null; _loadingAd = false; }, )); }

Future showRewardedAd() async { int tries = 0; int maxTries = 5;

if (_rewardedAd == null) {
  while (tries < maxTries) {
    if (!_loadingAd) {
      _createRewardedAd;
    }
    await Future.delayed(const Duration(seconds: 1));

    tries++;

    if (_rewardedAd != null) {
      break;
    } else if (tries >= maxTries) {
      await showDialog(
          context: context,
          builder: (BuildContext context) {
            return AlertDialog(
              title: const Text("Ad Error"),
              content: const Text(
                  "Ad taking longer to load. Check the Internet. Continue waiting?"),
              actions: <Widget>[
                Semantics(
                  button: true,
                  label: "OK",
                  child: TextButton(
                    child: const Text("OK"),
                    onPressed: () {
                      tries = -2;
                      Navigator.of(context).pop();
                    },
                  ),
                ),
                Semantics(
                  button: true,
                  label: "Cancel",
                  child: TextButton(
                    child: const Text("Cancel"),
                    onPressed: () {
                      //remove screen scaling ban
                      Navigator.of(context).pop();
                    },
                  ),
                ),
              ],
            );
          });
    }
  }
}

if (_rewardedAd == null) {
  if (!_loadingAd) {
    _createRewardedAd;
  }

  return;
}

_rewardedAd!.fullScreenContentCallback = FullScreenContentCallback(
  onAdDismissedFullScreenContent: (RewardedAd ad) {
    ad.dispose();
    _rewardedAd = null;
  },
  onAdFailedToShowFullScreenContent: (RewardedAd ad, AdError error) async {
    ad.dispose();
    _rewardedAd = null;
    //_createRewardedAd;
  },
);
await _rewardedAd!.show(
    onUserEarnedReward: (AdWithoutView ad, RewardItem reward) {
  print("rewarded");
});

}

Future _initAds() async { await MobileAds.instance.initialize(); await _createRewardedAd; return true; }

@override Widget build(BuildContext context) { return SafeArea( child: Scaffold( appBar: AppBar( title: Text(widget.title), ), body: FutureBuilder( future: _initAds(), builder: (context, snapshot) { if (snapshot.hasData) { return const Center( child: Text( 'Click to show test ad', ), ); } else { return const Center( child: SizedBox( width: 60, height: 60, child: CircularProgressIndicator( strokeWidth: 8.0, color: Color.fromRGBO(69, 162, 158, 1.0), ), ), ); } }), floatingActionButton: FloatingActionButton( onPressed: _adBuyDialog, tooltip: 'Show Ad', child: const Icon(Icons.add), ), ), ); } }

4. Add to `Android Manifest':

<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-3940256099942544~3347511713"/>

5. Run app. Click on + button, then "watch ad" button. While the ad is playing user cannot stop it. Back button does not work. Close (X) button does not work

**Expected results:**
User can interrupt ad playback by using Android back button or clicking close button in the ad

**Actual results:** 
Ad is unstoppable

Hi @under3415 There was a similar issue here as well. It looks like an issue from ads library rather than this Flutter ads plugin since I also see the issue with Android native reward sample code (you can try it to check this).

Also, I see there is a related issue that you can take a look on it: https://groups.google.com/g/google-admob-ads-sdk/c/4BGujai2Cig/m/3t2tuJmfBgAJ

We can close it if it is not a flutter issue. There is no related issue that is in progress though. This whole system of bug reporting is starting to feel like an exercise in stalling and finger pointing, very unproductive. I thought ads were Google's number one priority, it is their bread and butter, it is surprising how little they seem to care! :-D

[huycozy]

I watch some rewarded ads recently on apps/games and see it also can not be closed until it finished (even pressing back button or close button on the top corner). So I think it could be a change with ads activity that's out of the scope of this flutter plugin.

I will close this issue from here. If you disagree, please write in the comments and I will reopen it. Thanks!

OK to close it. Is there somewhere else I could file this bug for the Google ads team?
