Future<bool> preloadInterstitialAd({

  AdRequestConfig? requestConfig,
}) async {
  _validateAdUnitId(adUnitId);
  try {
    final params = <String, dynamic>{
      'adUnitId': adUnitId,
    };

    if (requestConfig != null) {
      params.addAll(requestConfig.toMap());
    }

    final result = await _channel.invokeMethod<bool>(
      'preloadInterstitialAd',
      params,
    );
    return result ?? false;
  } catch (e) {
    debugPrint('Error loading interstitial ad: $e');
