show method

Future<bool> show()

Shows the preloaded interstitial ad.

Returns true if the ad was shown, false if:

• No ad is loaded
• The frequency cap interval has not elapsed

After a successful show, the next ad is automatically preloaded.

Implementation

Future<bool> show() async {
  if (_isDisposed) return false;
  if (_state != AdState.ready) return false;
  if (!_frequencyCap.canShow) return false;

  _state = AdState.showing;
  final resolvedId = adUnitId.resolved(adType: AdType.interstitial);

  // In production, this would call interstitialAd.show()
  _frequencyCap.recordImpression();
  _emitEvent(AdEvent(type: AdEventType.shown, adUnitId: resolvedId));

  _state = AdState.idle;

  // Auto-preload next
  unawaited(load());
  return true;
}
