testDeviceId's are not working in google-mobile-ads flutter - flutter

Question

I was trying to set my test device id with the requestConfiguration. For checking whether setup for testdevice is successful, I filtered logcat in android studio with setTestDeviceIds but it's showing me the following log
2021-03-31 04:17:36.907 27185-27185/? I/Ads: Use RequestConfiguration.Builder().setTestDeviceIds(Arrays.asList("xxxxxxxxxxxxxxxxxxx")) to get test ads on this device.
So setting up for test device are not working and I can't test with real ads. As I'm passing testDeviceId's this log was supposed to not appear. You can see I'm passing testDeviceId's for both in RequestConfiguration and bannerAd.
Steps to reproduce
Here is my main.dart file
import 'package:flutter/material.dart';
import 'package:google_mobile_ads/google_mobile_ads.dart';
import 'package:provider/provider.dart';
import 'package:us/global/theme/app_themes.dart';
import 'package:us/utils/ad_helper.dart';
void main() {
WidgetsFlutterBinding.ensureInitialized();
MobileAds.instance.initialize().then((InitializationStatus status) {
print('Initialization done: ${status.adapterStatuses}');
MobileAds.instance
.updateRequestConfiguration(RequestConfiguration(
testDeviceIds: AdHelper.allTestDevices));
});
runApp(
MyApp()
);
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return ChangeNotifierProvider<ThemeChanger>(
create: (_) => ThemeChanger(),
child: new MaterialAppWithTheme(),
);
}
}
class MaterialAppWithTheme extends StatelessWidget {
#override
Widget build(BuildContext context) {
final theme = Provider.of<ThemeChanger>(context);
return MaterialApp(
title: 'Const',
debugShowCheckedModeBanner: false,
theme: theme.getDarkTheme ? ThemeData.dark():ThemeData.light(),
home: HomeScreen(),
);
}
}
class HomeScreen extends StatefulWidget {
#override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
static final AdRequest request = AdRequest(
testDevices: AdHelper.allTestDevices,
);
BannerAd _bannerAdd;
bool _isBannerAdLoaded = false;
Future<InitializationStatus> _initGoogleMobileAds() {
// TODO: Initialize Google Mobile Ads SDK
return MobileAds.instance.initialize();
}
#override
void initState() {
super.initState();
_bannerAdd = BannerAd(
adUnitId: AdHelper.homePageBannerAd,
size: AdSize.banner,
request: request,
listener: AdListener(
onAdLoaded: (_) { // Future<SharedPrefData> _setDarkMode(bool darkMode) async{
// SharedPreferences prefs = await SharedPreferences.getInstance();
// log.i('Current dark mode $darkMode.');
// await prefs.setBool('darkmode', darkMode);
// log.i('Dark mode toggled successfully');
// return await getPersistedData();
// }
setState(() {
_isBannerAdLoaded = true;
});
},
onAdFailedToLoad: (ad, error) {
// Releases an ad resource when it fails to load
ad.dispose();
print('Ad load failed (code=${error.code} message=${error.message})');
},
),
);
_bannerAdd.load();
}
#override
Widget build(BuildContext context) {
//this gonna give us total height and with of our device
return Scaffold(
// bottomNavigationBar: BottomNavBar(),
body: Stack(
children: <Widget>[
SafeArea(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
this._isBannerAdLoaded? Container(
margin: EdgeInsets.only(bottom: 35),
height: 72.0,
alignment: Alignment.center,
child: AdWidget(ad: _bannerAdd),
):Text('')
],
),
),
)
],
),
);
}
}
Here is my adhelper.dart file
import 'dart:io';
class AdHelper{
static String TEST_BANNER_AD = "ca-app-pub-3940256099942544/6300978111";
static String get homePageBannerAd{
if(Platform.isAndroid){
return TEST_BANNER_AD;
}
else if(Platform.isIOS){
return TEST_BANNER_AD;
}
else
throw new UnsupportedError("Platform is not supported..");
}
static List<String> get allTestDevices{
String MY_REDMI_NOTE_9="xxxxxxxxxxx";
return [MY_REDMI_NOTE_9];
}
}

Answer 1

In my case this works
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await MobileAds.instance.initialize().then((InitializationStatus status) {
print('Initialization done: ${status.adapterStatuses}');
MobileAds.instance.updateRequestConfiguration(
RequestConfiguration(
tagForChildDirectedTreatment:
TagForChildDirectedTreatment.unspecified,
testDeviceIds: <String>["list of test device ids seprated by ,(comas)"]),
);
});
runApp(MyApp());
}

Answer 2

you can do it like this
void main() async {
WidgetsFlutterBinding.ensureInitialized();
MobileAds.instance.initialize();
// thing to add
RequestConfiguration configuration = RequestConfiguration(testDeviceIds: ['E46609DD331AF2754D38B3DCE3ED011B']);
MobileAds.instance.updateRequestConfiguration(configuration);
runApp(const MyApp());
}
