From the data you have posted, you are not using the most up to date version of the Google AdMob plugin for Flutter. Your version is 0.11.0 and the newest one is 0.13.0.

I would highly suggest you upgrade this plugin and see if this fixes your issue.

You might also want to consider going over the Get Stared guide to make sure you haven't missed anything.

Furthermore, when researching online , I found this thread related to the problem you are having in Unity. It seems there has been a deprecation and a creation of a new initialization API and I think that the current version of the plugin is not suited for it.

Thank you for your answer , I already had used the last version of google_mobile_ads but same issue had faced pluse another issue related to firebase although i didn't use or implement firbase at all . — AhmedSh, Jun 14 '21 at 10:24
