Flutter interstitial ad with AppOpen ads - flutter

Question

Currently Im using native_admob_flutter for my flutter app. I also included AppOpenAds and Interstital ad within the app.
I want to display the AppOpen ad when user open the app/ resume to the app, here is how I do it in main.dart:
#override
Future<void> didChangeAppLifecycleState(AppLifecycleState state) async {
switch (state) {
case AppLifecycleState.resumed:
loadAndDisplayAppOpenAd();
break;
case AppLifecycleState.inactive:
break;
case AppLifecycleState.paused:
break;
case AppLifecycleState.detached:
break;
}
}
However I found that displaying Interstial ad will also change the app state -> inactive -> paused -> resume, which trigger AppOpen ad.
This really create bad user experinence. Is there a way to overcome this? Thank you!

You may need a variable to make sure that app has been paused by user action, and not by interstitial.
static bool pausedByInterstitial = false;
...
class AppLifecycleReactor extends WidgetsBindingObserver {
final AppOpenAdManager appOpenAdManager;
AppLifecycleReactor({required this.appOpenAdManager});
static bool pausedByInterstitial = false;
#override
Future<void> didChangeAppLifecycleState(AppLifecycleState state) async {
if (state == AppLifecycleState.resumed && !pausedByInterstitial) {
appOpenAdManager.showAdIfAvailable();
}
}
}
...
showInter() {
AppLifecycleReactor.pausedByInterstitial = true;
InterstitialListener(
...
onAdHiddenCallback: (ad) {
AppLifecycleReactor.pausedByInterstitial = false;
},
...
);
}
