How show interstitial ads by number of clicks (google_mobile_ads)

Question

I want to show an interstitial ads in 10 clicks. Is there a way to do this? Or how I can show only 1 time at the opening of the app? I'm just trying to find how to use it.

 ElevatedButton(
          child: Text("Ads"),
          onPressed: () {
            _interstitialAd.show();
            Navigator.push(context,
                MaterialPageRoute(builder: (context) => PageTwo()));
          },
        ),

You need to keep a counter in your state somewhere and and call the method to show the ad only when it's a multiple of 10.

//A field of your state class
int counter = 0;

//...somewhere in build
ElevatedButton(
  child: Text("Ads"),
  onPressed: () {
    if(counter%10 == 0) {
      _interstitialAd.show();
    }

    counter++;
    Navigator.push(context,
      MaterialPageRoute(builder: (context) => PageTwo()));
  },
),
