Blank screen after few seconds

Plugin Version

google_mobile_ads: ^0.13.5

Steps to Reproduce

I am not sure how to reproduce this, I have a lot of code and it started happening after I added googleads-mobile-flutter to it. I know it is very hard to determine what is happening without reproducing the error, but at least someone could have a clue about this problem.

Expected results: Application runs normal and ads shown.

Actual results: Widgets get “blank” after some seconds, everything works normal (i.e. buttons, methods, classes).

Issue Really seems like some rendering problem. I also thought could be some memory leak or something, but memory test on dev tools does not point it. Also I read something about android garbage collector and flutter embedding. I only happens when ads are active (if user gets premium it stops happening). Seems that it occurs when webview is destroyed (log: “W/Ads (13786): 004 The webview is destroyed. Ignoring action.”)

But this then also doesn’t compile and throws errors related to Kotlin version.

Running on Windows with an Android virtual device. Using Flutter Stable channel. Thanks.

@mattf80 please file this as a separate issue to track.

Hi @brunodmn, Thanks for filing the issue. I can understand creating a reproducible code might not be easy, But can you please provide some more info

• Is this issue reproducible only with a specific ad/ device/ or Platform (IOS)
• Does this issue occur on a newly created sample app with an ad too?
• Can you please try to determine the reproducible steps, and whether this occurs 100% of the time or is intermittent?

On a side note, can you please try upgrading to the latest plugin 0.13.6, and see if you are still able to reproduce the issue?

Thanks

Hi @maheshmnj, it happens every time, some times after few seconds, sometimes few minutes. I’ve noticed if I try to login with Google (firebase_auth/google_sign_in) it happens right away. I have tried with Android only. I don’t think it’s with some specific ad, I tried removing banner and keeping intersticial, and the other way around, same results. I did upgrade to latest version 0.13.6 and it keeps going. I will create a new app and try to reproduce by today, I’ll keep you posted. Thank you.
