How to rename the app Bundle name from Android gradle with multiple product flavors?

Question

As I was able to rename the APK using this way but could not get how to rename App Bundle with multiple flavors.

android.applicationVariants.all { variant ->
    variant.outputs.all { output ->
        output.outputFileName = "${variant.getFlavorName()}-${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}-${output.getFilter(com.android.build.OutputFile.ABI)}.apk"
    }
}

Here are my app flavors and split APK code

productFlavors {
    aFlavor {
        applicationId "com.a"

        
        versionCode 5
        versionName "1.0.5"

        signingConfig signingConfigs.signingA
    }
    bFlavor {
        applicationId "com.b"

        versionCode 5
        versionName "1.0.5"

        signingConfig signingConfigs.signingB
    }
    cFlavor {
        applicationId "com.c"

        versionCode 3
        versionName "1.0.3"

        signingConfig signingConfigs.signingC
    }
}

splits {
    abi {
        enable true
        reset()
        include 'arm64-v8a', 'x86', 'x86_64'
        universalApk false
    }
}

Try this approach:

applicationVariants.all { variant ->
    variant.outputs.all { output ->
        output.outputFileName = "${variant.getFlavorName()}-${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}-${output.getFilter(com.android.build.OutputFile.ABI)}.apk"
    }

    tasks.named("sign${variant.name.capitalize()}Bundle", com.android.build.gradle.internal.tasks.FinalizeBundleTask) {
        File file = finalBundleFile.asFile.get()
        File finalFile = new File(file.parentFile, "${variant.getFlavorName()}-${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}.aab")
        finalBundleFile.set(finalFile)
    }
}

It uses an internal gradle task FinalizeBundleTask which has getter and setter for final bundle file name.
