Note
Examples showing how all the format types work are available in the demo project.

Example of creating an interstitial ad
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:yandex_mobileads/mobile_ads.dart';
class InterstitialPage extends StatefulWidget {
const InterstitialPage({super.key});
@override
State<InterstitialPage> createState() => _InterstitialPageState();
}
class _InterstitialPageState extends State<InterstitialPage> {
static const _tag = 'Interstitial';
static const _adUnitId = 'demo-interstitial-yandex';
final InterstitialAdLoader _loader = InterstitialAdLoader();
InterstitialAd? _ad;
String _status = 'Initializing...';
@override
void initState() {
super.initState();
_init();
}
@override
void dispose() {
_ad?.destroy();
super.dispose();
}
Future<void> _init() async {
setState(() => _status = 'Loading ad...');
try {
final ad = await _loader.loadAd(
adRequest: AdRequest(adUnitId: _adUnitId),
);
if (!mounted) {
ad.destroy();
return;
}
_ad = ad;
setState(() => _status = 'Showing...');
await _show();
} on AdRequestError catch (error) {
debugPrint('[$_tag] onAdFailedToLoad: ${error.description}');
if (mounted) setState(() => _status = 'Error: ${error.description}');
}
}
Future<void> _show() async {
final ad = _ad;
if (ad == null) return;
ad.setAdEventListener(
eventListener: InterstitialAdEventListener(
onAdShown: () => debugPrint('[$_tag] onAdShown'),
onAdDismissed: () {
debugPrint('[$_tag] onAdDismissed');

}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Interstitial')),
body: Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
const CircularProgressIndicator(),
const SizedBox(height: 16),
Text(_status),
],
),
),
