[firebase_admob] Full Banner width is not covering the area on phone width.

[habilgur]

Hello everyone.
When i used smart banner with Admob.testId there was always return failedtoLoad:3 error and there was also error and blank container in some apps that released in market with real Admob Id's.
So I decided to use FullBanner Size as a alternative but fullbanner sometimes showing up with not covering to whole area.
Does any one know why is that happening?
Do you think Is this issue will be fixed when release app to market?
Thank you.
