Understanding Native Ads:

Unlike traditional ads or interstitial ads, Native ads are like natural goods, and provide advertising and marketing that is not obvious, easy to the person, It also allows the average user to enjoy themselves.

AdMob Native Ads supports customizable templates and advertisements that are allowing developers to customize the types of ads to match the quality in their app. Developers can also choose small, medium and large ad components that first-rate in shape their app design.

Improved Ad Performance – Native ads layout displays in the proper way to all devices. It provides best results compare to other ad formats like Banner, Adaptive Banner or App Open ads. Their nature reduces ad blindness and banner fatigue resulting in higher conversion rates for advertisers.

Let’s start How to add Admob Native Ads to the Flutter App

Step 1: Create a new Project

1. Open Android Studio.
2. Click on New Flutter Project.
3. Make sure you have selected your Flutter SDK Path. Click Next
4. Enter the Project Name, Project Location (where you need to put the project),
5. Select the project type (Default Application).
6. Enter Organization
7. Select Android and iOS languages (default: Kotlin and Swift).
8. Select Platforms (On which platform you want to run the project).
9. Click on Finish button.
10. Now wait for the project to finish building.

Step 2: Adding the Mobile Ads Package in the pubspec.yaml

• Open the pubspec.yaml file from the left panel of the project directory.
• Add the google_mobile_ads package under dependencies.

google_mobile_ads: ^3.0.0

• Click on Pub get to retrieve packages in the project.
• Go to android/build.gradle and import the below dependencies.

dependencies {
    classpath 'com.android.tools.build:gradle:7.3.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.15'
}

• Go to android/app/build.gradle and import the below plugin.

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.google.gms.google-services'

• Make sure you have already added the google-services.json file in the android/app level folder.

 

Step 3: Modify AndroidManifest.xml

• Add the internet permission to the Android Manifest file. Go to android/app/src/main/AndroidManifest.xml
• Add internet permission before <application> tag

<uses-permission android:name="android.permission.INTERNET"/>

• Now we add our AdMob AppId to your in AndroidManifest file by adding the <meta-data> tag inside the <application> tag

<manifest>

    <application>

           <meta-data
                 android:name="com.google.android.gms.ads.APPLICATION_ID"
                 android:value="ca-app-pub-3940256099942544~3347511713"/>

    </application>

</manifest> 

Step 4: Implement code to display native ads.

• initialize the Mobile Ads SDK in main.dart file

void main() async{

  WidgetsFlutterBinding.ensureInitialized();
  MobileAds.instance.initialize();
  runApp(const MyApp());

}

• Let’s add the home.dart file to your lib folder.
• Import google_mobile_ads package on top.

import 'package:google_mobile_ads/google_mobile_ads.dart';

• Create native ad object

//creating Object of NativeAd

NativeAd? _nativeAd;

• Create the ad objects and load ads.

// Create the ad objects and load ads.
    _nativeAd = NativeAd(
      adUnitId: '/6499/example/native',  // Test ID :- /6499/example/native
      request: AdRequest(),
      listener: NativeAdListener(
        onAdLoaded: (Ad ad) {
          print('$NativeAd loaded.');
          setState(() {
            //_nativeAdIsLoaded = true;
          });
        },
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          print('$NativeAd failedToLoad: $error');
          ad.dispose();
        },
        onAdOpened: (Ad ad) => print('$NativeAd onAdOpened.'),
        onAdClosed: (Ad ad) => print('$NativeAd onAdClosed.'),
      ),
      nativeTemplateStyle: NativeTemplateStyle(
        templateType: TemplateType.medium,
        mainBackgroundColor: Colors.white12,
        callToActionTextStyle: NativeTemplateTextStyle(
          size: 16.0,
        ),
        primaryTextStyle: NativeTemplateTextStyle(
          textColor: Colors.black38,
          backgroundColor: Colors.white70,
        ),
      ),
    )..load();

• There are two types of native ads in TemplateType. (1) Medium (2) Small
• Display native ads using the widget.

Padding(
              padding: const EdgeInsets.only(top:10.0),
              child: ConstrainedBox(
                constraints: const BoxConstraints(
                  minWidth: 300,
                  minHeight: 350,
                  maxHeight: 400,
                  maxWidth: 450,
                ),
                child: AdWidget(ad: _nativeAd!),
              ),
            )

• Remove the native ads object by using the below method.

@override
  void dispose() {
    super.dispose();
    _nativeAd?.dispose();
  }

Step 5: Implement full code to display admob native ads in the home.dart file.

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



class Home extends StatefulWidget {
  const Home({Key? key}) : super(key: key);

  @override
  State<Home> createState() => _HomeState();
}

class _HomeState extends State<Home> {

//creating Object of NativeAd
NativeAd? _nativeAd;


@override
  void initState() {
    // TODO: implement initState
    super.initState();
    loadNativeAd();
  }

@override
  void dispose() {
    super.dispose();
    _nativeAd?.dispose();
  }

void loadNativeAd(){

// Create the ad objects and load ads.
    _nativeAd = NativeAd(
      adUnitId: '/6499/example/native',  // Test ID :- /6499/example/native
      request: AdRequest(),
      listener: NativeAdListener(
        onAdLoaded: (Ad ad) {
          print('$NativeAd loaded.');
          setState(() {
            //_nativeAdIsLoaded = true;
          });
        },
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          print('$NativeAd failedToLoad: $error');
          ad.dispose();
        },
        onAdOpened: (Ad ad) => print('$NativeAd onAdOpened.'),
        onAdClosed: (Ad ad) => print('$NativeAd onAdClosed.'),
      ),
      nativeTemplateStyle: NativeTemplateStyle(
        templateType: TemplateType.medium,
        mainBackgroundColor: Colors.white12,
        callToActionTextStyle: NativeTemplateTextStyle(
          size: 16.0,
        ),
        primaryTextStyle: NativeTemplateTextStyle(
          textColor: Colors.black38,
          backgroundColor: Colors.white70,
        ),
      ),
    )..load();
}

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Native Ads',
            style: TextStyle(fontSize: 18.0, color: Colors.white)),
        backgroundColor: Colors.indigo,
        centerTitle: true,
        iconTheme: const IconThemeData(color: Colors.white),
      ),
      body: Container(
         child: Padding(
           padding: const EdgeInsets.only(top:10.0),
           child: ConstrainedBox(
             constraints: const BoxConstraints(
               minWidth: 300,
               minHeight: 350,
               maxHeight: 400,
               maxWidth: 450,
             ),
             child: AdWidget(ad: _nativeAd!),
           ),
         ),
       ),
    );
  }
}

 

Step 6: All set! Run the project. See the screenshots of google native ads below.

Medium Native ad show at the top of the user device screen

 

Small Native ad show at the top of the user device screen

 

Conclusion
