App crashing with null object[0] in iOS

I am using rewarded and interstitial ads. It is failing in initialisation itself. Also it is mentioning to mention test device id which I already specified as per example and device if as per log.I followed all the steps as mentioned in pub.Dev

Android it is working fine.

Plugin version

0.13.0

Steps to reproduce

Unable to initialise itself

1. Run flutter create bug.
2. Update the files as follows: …
3. …

Expected results: app should open Actual results: failed with adding null ad. If I comment ads the app is working fine.no issues in android.

adding MobileAds.instance.initialize(); in init and WidgetsFlutterBinding.ensureInitialized(); solved the issue.

Hello @EArminjon

By the way I am using Macbook M1 chip

Sorry i just copied the code from my main code. Below is the formatted code.

  InterstitialAd? _interstitialAd;
  RewardedAd? _rewardedAd;
  int _numInterstitialLoadAttempts = 0;
  int maxFailedLoadAttempts = 5;
  int _numRewardedLoadAttempts = 0;

  void _createInterstitialAd() {
    InterstitialAd.load(
        adUnitId: InterstitialAd.testAdUnitId,
        request: request,
        adLoadCallback: InterstitialAdLoadCallback(
          onAdLoaded: (InterstitialAd ad) {
            print('$ad loaded');
            _interstitialAd = ad;
            _numInterstitialLoadAttempts = 0;
          },
          onAdFailedToLoad: (LoadAdError error) {
            print('InterstitialAd failed to load: $error.');
            _numInterstitialLoadAttempts += 1;
            _interstitialAd = null;
            if (_numInterstitialLoadAttempts <= maxFailedLoadAttempts) {
              _createInterstitialAd();
            }
          },
        ));
  }

  void _showInterstitialAd() {
    if (_interstitialAd == null) {
      print('Warning: attempt to show interstitial before loaded.');
      return;
    }
    _interstitialAd!.fullScreenContentCallback = FullScreenContentCallback(
      onAdShowedFullScreenContent: (InterstitialAd ad) =>
          print('ad onAdShowedFullScreenContent.'),
      onAdDismissedFullScreenContent: (InterstitialAd ad) {
        print('$ad onAdDismissedFullScreenContent.');
        ad.dispose();
        _createInterstitialAd();
      },
      onAdFailedToShowFullScreenContent: (InterstitialAd ad, AdError error) {
        print('$ad onAdFailedToShowFullScreenContent: $error');
        ad.dispose();

      },

    _interstitialAd!.show();
    _interstitialAd = null;
