Flutter App Monetization Tricks (AdMob + In-App Purchases) – 2025 Guide

Looking to turn your Flutter app into a money-making machine?
You’re in the right place! In this guide, we’ll explore practical and powerful ways to monetize your Flutter apps using AdMob Ads and In-App Purchases (IAP) — both beginner and pro-friendly.

Monetize with Google AdMob (Updated for 2025)

How to Set It Up:

1. Sign up at Google AdMob.
2. Register your app (Android/iOS).
3. Add the official Flutter plugin:

dependencies:
  google_mobile_ads: ^5.0.0

4.Initialize AdMob in your main.dart:

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  MobileAds.instance.initialize();
  runApp(MyApp());
}

Banner Ad Example:

BannerAd _bannerAd = BannerAd(
  adUnitId: 'ca-app-pub-xxxxxxxxxxxxxxxx/xxxxxxxxxx',
  size: AdSize.banner,
  request: AdRequest(),
  listener: BannerAdListener(),
)..load();

Tips to Boost Ad Revenue:

• Show Interstitial Ads smartly between screens.
• Use Native Ads to blend ads into the UI (higher CTR).
• Explore AdMob Mediation for increased fill rate and CPM.
• Don’t overuse ads – keep UX in mind!

2. In-App Purchases (IAP) – Sell Features or Content

In-App Purchases allow you to sell digital goods or unlock features inside your app. Perfect for:

• Premium features
• Remove Ads
• Digital content (eBooks, stickers, plugins)

in_app_purchase: ^3.1.5

Setup Steps:

1. Configure products in Google Play Console / Apple App Store Connect.
2. Fetch product details in Flutter:

final ProductDetailsResponse response = await InAppPurchase.instance.queryProductDetails({'pro_upgrade'});

Handle purchase:

InAppPurchase.instance.buyNonConsumable(
  purchaseParam: PurchaseParam(productDetails: product),
);
