App crashes on Android 10, flutter beta channel

[jeromeDms]

Dear All
I'm facing multiple crashes reported by google play console, with the following trace, all crashes are for devices running Android 10, different devices (most of them seem Redmi)
I cannot find a clear way to solve this, after multiple hours searching.
I'm using flutter beta channel (Because it improves a lot the performances when displaying AdMob ads).
Any help would be greatly appreciated.

Hi @jeromeDms, thanks for filing the issue. Can you please share the complete logs? Also, does the app crash when running the app locally (Not downloaded from playstore)? if yes, Please share the complete output of flutter run -v in a text file.

[jeromeDms]

Unfortunately I'm not able to reproduce this issue from a real device (I only own 2), nor from the emulator.
This issue was not present until I switched to the beta channel.
Crashlytics does not show those errors, I only see them in the play console crash reports.
Below the concerned devices, from the play console.
Thanks for any help you can provide.
Jerome

Thanks for the info @jeromeDms, I am not sure if this backtrace would help. Do you have a symoblicable crash logs?

[jeromeDms]

Btw, the flutter version mentioned in flutter doctor is not the one resulting in those crashes (I updated flutter before creating this post).
The flutter beta version was the one before version 2.13.0-0.2.pre
Don't know if 2.13.0-0.2.pre could help to solve the crashes I mentioned ?

When exploring the app bundle in play console, I can see the symbolication files mapping.txt (3.58Mb) as well as the native debug symbol file native-debug-symbols.zip (Only 5.12K).
Reading play console support, those files should be enough to symbolicate backtrace, but it seems not.

debug-symbols file is only 5.12K, looks weird.

I used the following in build.gradle

defaultConfig {
  ndkVersion "24.0.8215888"
        ndk {
            debugSymbolLevel 'FULL'
        }
}

buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

And the proguard-rules.pro is

-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.** { *; }
-keep class io.flutter.util.** { *; }
-keep class io.flutter.view.** { *; }
-keep class io.flutter.** { *; }
-keep class io.flutter.plugins.** { *; }
-keep class com.google.firebase.** { *; }
-keep class com.shatsy.** { *; }

What can we do to find a solution to this ?
Should I revert back to Flutter stable version and forget the performance improvements using Admob ?
