Unable to destroy activity Android: Google Play Console Error

I am trying to launch my app into Production on Google Playstore. I have used Flutter to create the app. But in the pre-launch report I am getting error:

Stacktrace:

I try to find anything discussing this and I found one Stackoverflow question which was recieved badly and downvoted; Here's a ref to the post. I am not to sure why this is happening and I am not sure whether it is external problem which I can fix or an internal bug.

When I downloaded the app from the Playstore when it was production, it displayed a white screen when I opened it and stayed like this. I am not sure if me getting this error is a result of that or not either.

Any help on the matter will be appreciated!

Solution

  • I have managed to fix both problems which I was having. I fixed the first problem of this error by updating file_picker library to version 2.10. The issue was fixed in version 2.0.12. I also fixed the second issue of the white screen in the app when it started by downgrading to: classpath 'com.android.tools.build:gradle:3.4.3'. Here's the reference to the post which helped me.
