Please help me!

It looks like that's a known issue with the OneSignal Grandle plugin.

Github OneSignal Issue

In the discussion some solutions are proposed, by they seem to broke OneSignal or to cause more issue.

Two of them are:

• Place onesignal plugin after it in the sequence in the "android/app/build.gradle". Credit: Direnalex comment
• Downgrade Flutter and Kotlin. Credit: Dgilperez comment

My suggestion is to bring attention to the Github Issue so that it can be solved by the OneSignal community.
