What's the difference between this plugin and firebase_admob?

[jezsung]

I'm wondering if there's any optimization difference between this plugin and the official AdMob library firebase_admob. Since the official library looks somehow linked to Firebase and this one does not. I'm using Firebase for my primary backend, will be there any optimization difference?

I have the same question but I choose this plugin instead of firebase_admob because I don't want to set up another project on Firebase.
