Admob Manager Flutter

This is a customized package of Easy Ads Flutter package.

Features

• Google Mobile Ads (banner, appOpen, interstitial, rewarded ad)

Platform Specific Setup

iOS

Update your Info.plist

Update your app's ios/Runner/Info.plist file to add two keys:

<key>GADApplicationIdentifier</key>
<string>YOUR_SDK_KEY</string>

• You have to add SKAdNetworkItems for all networks provided by admob-manager info.plist you can copy paste SKAdNetworkItems in your own project.

Android

Update AndroidManifest.xml

<manifest>
    <application>
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>
    </application>
</manifest>

Initialize Ad Ids

import 'dart:io';

import 'package:admob_manager_flutter/admob_manager_flutter.dart';
import 'package:google_mobile_ads/google_mobile_ads.dart';

class TestAdIdManager extends IAdIdManager {
  const TestAdIdManager();

  @override
  AppAdIds? get admobAdIds => AppAdIds(
    appId: Platform.isAndroid
        ? 'ca-app-pub-3940256099942544~3347511713'
        : 'ca-app-pub-3940256099942544~1458002511',
    appOpenId: Platform.isAndroid
        ? 'ca-app-pub-3940256099942544/3419835294'
        : 'ca-app-pub-3940256099942544/5662855259',
    bannerId: 'ca-app-pub-3940256099942544/6300978111',
    interstitialId: 'ca-app-pub-3940256099942544/1033173712',
    rewardedId: 'ca-app-pub-3940256099942544/5224354917',
  );
}

Initialize the SDK

Before loading ads, have your app initialize the Mobile Ads SDK by calling AdmobManager.instance.initialize() which initializes the SDK and returns a Future that finishes once initialization is complete (or after a 30-second timeout). This needs to be done only once, ideally right before running the app.

import 'package:admob_manager_flutter/admob_manager_flutter.dart';
import 'package:flutter/material.dart';

const IAdIdManager adIdManager = TestAdIdManager();

AdmobManager.instance.initialize(
    adIdManager,
    adMobAdRequest: const AdRequest(),
    // Set true if you want to show age restricted (age below 16 years) ads for applovin
    isAgeRestrictedUserForApplovin: true,
    // To enable Facebook Test mode ads
    fbTestMode: true,
    admobConfiguration: RequestConfiguration(testDeviceIds: [
      '072D2F3992EF5B4493042ADC632CE39F', // Mi Phone
      '00008030-00163022226A802E',
    ]),
  );

Interstitial/Rewarded Ads

Load an ad

Ad is automatically loaded after being displayed or first time when you call initialize. But on safe side, you can call this method. This will load both rewarded and interstitial ads. If a particular ad is already loaded, it will not load it again.

AdmobManager.instance.loadAd();

Show interstitial or rewarded ad

AdmobManager.instance.showAd(AdUnitType.rewarded);

Show random interstitial ad

AdmobManager.instance.showRandomAd(AdUnitType.interstitial)

Show appOpen ad

AdmobManager.instance.showAd(AdUnitType.appOpen)

Show Banner Ads

This is how you may show banner ad in widget-tree somewhere:

@override
Widget build(BuildContext context) {
  Column(
    crossAxisAlignment: CrossAxisAlignment.stretch,
    children: [
      SomeWidget(),
      const Spacer(),
      AdmobBannerAdWidget(adSize: AdSize.mediumRectangle),
    ],
  );
}

Listening to the callbacks

Declare this object in the class

  StreamSubscription? _streamSubscription;

We are showing InterstitialAd here and also checking if ad has been shown. If true, we are canceling the subscribed callbacks, if any. Then, we are listening to the Stream and accessing the particular event we need

if (AdmobManager.instance.showInterstitialAd()) {
  // Canceling the last callback subscribed
  _streamSubscription?.cancel();
  // Listening to the callback from showInterstitialAd()
  _streamSubscription =
  AdmobManager.instance.onEvent.listen((event) {
    if (event.adUnitType == AdUnitType.interstitial &&
        event.type == AdEventType.adDismissed) {
      _streamSubscription?.cancel();
      goToNextScreen(countryList[index]);
    }
  });
}
