GAM setup flutter

Setting up Google Ad Manager (GAM) for a Flutter app involves integrating the GAM SDK into your Flutter project, creating ad units, setting up line items and creatives, and displaying ads within your app. Here's a step-by-step guide to help you set up GAM for Flutter:

Step 1: Create a Google Ad Manager Account

If you don't have a Google Ad Manager account, you'll need to create one by visiting and signing up.

Step 2: Set Up an Application in Google Ad Manager

  1. Log in to your Google Ad Manager account.
  2. Click on "Inventory" in the left sidebar.
  3. Under "Ad units," click "Ad units."
  4. Click the "+ New ad unit" button.
  5. Fill in the ad unit details, including the name, ad type (e.g., banner, interstitial), size, and targeting options.
  6. Save the ad unit and take note of the ad unit ID.

Step 3: Integrate the GAM SDK into Your Flutter App

  1. Add the google_mobile_ads package to your pubspec.yaml file:
            sdk: flutter
        google_mobile_ads: ^latest_version
  2. Run flutter pub get to install the package.

Step 4: Initialize the GAM SDK in Your App

  1. Import the google_mobile_ads package in your Dart file:
    import 'package:google_mobile_ads/google_mobile_ads.dart';
  2. Initialize the GAM SDK by adding the following code in your main function or wherever you initialize your Flutter app:

Step 5: Request and Display Ads

  1. Create a banner or interstitial ad widget in your Flutter app
        ad: BannerAd(
            size: AdSize.banner,
            adUnitId: 'YOUR_AD_UNIT_ID',
            request: AdRequest(),
            listener: BannerAdListener(),
  2. Replace 'YOUR_AD_UNIT_ID' with the actual ad unit ID you obtained from GAM.

Additional Steps

  • Customize the ad appearance and behavior using the provided ad widget properties and listeners.
  • For interstitial ads, use the InterstitialAd class to create and display interstitial ads with appropriate listeners.
  • Implement ad event listeners to handle ad lifecycle events, such as ad loaded, ad failed to load, ad clicked, etc.
