Ads are not showing up in release mode

Ads not showing up in release mode

i want to try the solution mentioned here but i dont know how to

when the app is signed in debug it shows ads , but not in release mode

Create a file called proguard-rules.pro in your android/app directory.

Add this line of code to it:

 -keep class io.flutter.app.** { *; }
 -keep class io.flutter.plugin.** { *; }
 -keep class io.flutter.util.** { *; }
 -keep class io.flutter.view.** { *; }
 -keep class io.flutter.** { *; }
 -keep class io.flutter.plugins.** { *; }
 -keep class com.google.firebase.** { *; }
 -keep class com.shatsy.** { *; }

The most important being: -keep class com.google.firebase.** { *; } and -keep class com.shatsy.** { *; }

Now in your app level build.gradle file, add this to your buildType:

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

So that your buildType folder looks something like this:

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.debug
        }
    }

Then run flutter build apk --buildTypeName

Example:

flutter build apk --release

A quicker solution is to add minifyEnabled false to your release buildType in you app level build.gradle

EXPLANATION: Proguard is probably blocking your app from using the firebase_ads library. That's probably why your app runs in debug mode, but not after building the apk.

Try it, and see if it works.
