Ads are not showing on iOS devices - dart

Question

In flutter, we want to use AdMob.
We set as follows.
Because there may be relationships, we also write Firebase Analytics.
[pubspec.yaml]
dependencies:
flutter:
sdk: flutter
firebase_admob: ^0.5.7
firebase_analytics: ^1.0.3
[main.dart]
void main() {
// [Analytics]
FirebaseAnalytics().logAppOpen();
// [Initialize:AdMob]
FirebaseAdMob.instance.initialize(
appId: Platform.isAndroid
? 'ca-app-pub-xxxxxxxxxxxxxxxx~xxxxxxxxxx'
: 'ca-app-pub-yyyyyyyyyyyyyyyy~yyyyyyyyyy',
);
// [Create Banner Ad:AdMob]
createBannerAd()
..load()
..show(
anchorType: AnchorType.top,
);
runApp(MyApp());
}
final MobileAdTargetingInfo targetingInfo = new MobileAdTargetingInfo(
testDevices: Const.testDevices,
keywords: <String>[
'foo',
'bar',
],
birthday: new DateTime.now(),
childDirected: true,
gender: MobileAdGender.female,
);
// [Create Banner Ad:AdMob]
BannerAd createBannerAd() {
return new BannerAd(
adUnitId: Platform.isAndroid
? 'ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX'
: 'ca-app-pub-YYYYYYYYYYYYYYYY~YYYYYYYYYY',
size: AdSize.banner,
targetingInfo: targetingInfo,
listener: (MobileAdEvent event) {
print("BannerAd event $event");
},
);
}
We download the Firebase configuration file and place it in the following.
In Xcode's Target Membership, we have confirmed that it is set correctly.
/android/app/google-services.json
/ios/Runner/GoogleService-Info.plist
It is displayed normally on Android device.
However, it is not displayed on the iOS device.
The following log was output.

2018-08-29 11:21:59.757247+0900 Runner[459:115885] flutter: BannerAd event MobileAdEvent.failedToLoad
How should we implement [FIRApp configure]; in the flutter?
Is it unnecessary? We could not find it in the sample code.
Is our setting correct?
If we wait for a few more days, will mobileAdId not be pending?

In parallel with this question, we also contact AdMob.
Ads will not be shown using the following app ID and ad unit ID.
ca-app-pub-3940256099942544~1458002511
ca-app-pub-3940256099942544/2934735716

Answer 1

We tried several terminals.
[OK] ASUS Z017DA (Android)
[OK] iPad mini
[OK] iPhone 4s
[NG] iPhone 6 Plus
[NG] iPhone SE
We tried various changes but they were ineffective. However, today "No ad to show" suddenly ceased to occur. But the ad was not displayed yet.
We thought that ads might be displayed outside the screen. When we made the following settings, the ad was displayed in the place we expected.
_bannerAd
  ..load()
  ..show(
    anchorType: AnchorType.top,
    anchorOffset: 50.0,
  );
However, in the terminal normally displayed before the change, the ad was displayed shifted downward. We could not adopt this method because we can not try all the terminals.
Next, we placed the ad under the screen.
_bannerAd
  ..load()
  ..show(
    anchorType: AnchorType.bottom,
  );
In this case, we were able to confirm that ad is displayed normally on all terminals. We wanted to place the ad on top but we gave it up.
AnchorType.top may be incorrect in some cases.

Answer 2

-> Privacy then
-> Adverting then
-> Limit Ad Tracking Admob is now displayed when repeating on and off.
Perhaps it is bad that DeviceID is in the same state?
