how to properly integrate Admob in a flutter app

Question

I've been trying to add Admob to my flutter application, but it keeps crashing..

Here is what I've tried to do:

I've added This package to my pubspec.yaml

Then I've added this meta-data to my AndroidManifest.xml file:

<meta-data
  android:name="com.google.android.gms.ads.APPLICATION_ID"
  android:value="ca-app-pub-here-is-my_app_id_in_admob"/>

result

I get this error when I try to run the program (please note that I didn't add any ads to my .dart files yet`

   > File 'com.android.builder.files.ZipCentralDirectory@d8f9ce4' was deleted, but previous version not found in cache

You can run flutter clean and it will be solved

From your question, it is not clear whether you use Firebase. You are using the "firebase_admob" package, which requires Google Service file from Firebase inside your project. If you no need a Firebase, I recommend you package admob_flutter . This package simple and works fine in my projects (but it no support Firebase integration).
