Отсутствует AdActivity в AndroidManifest.xml

у меня эта ошибка

Я попытался решить проблему, как указано в этих отсутствует-адактивность-с-android-configchanges и AdView – отсутствует рекламная активность с android:configChanges в AndroidManifest.xml, но возникла та же проблема.

в профиле/AndroidManifest у меня есть

<manifest xmlns:android = "http://schemas.android.com/apk/res/android"
    package = "puns.jokes.org.jokespuns">
    <!-- Flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->

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

в main/AndroidManifest.xml

<manifest xmlns:android = "http://schemas.android.com/apk/res/android"
    package = "puns.jokes.org.jokespuns">

Что я здесь делаю неправильно?
