I was able to nail it down to the androidNativeBundle.

After removing the following lines:
android/build.gradle
classpath 'io.github.howardpang:androidNativeBundle:1.1.4'

app/build.gradle
apply plugin: 'com.ydq.android.gradle.native-aar.import'

externalNativeBuild {
    cmake {
        arguments.add(0, "-DANDROID_STL=c++_static")
    }
}

ndk {
    // Flutter does not currently support building for x86 Android (See Issue 9253).
    abiFilters("armeabi-v7a", "x86_64", "arm64-v8a")
}

externalNativeBuild {
    cmake {
        setPath("CMakeLists.txt")
    }
}

I was able to build the example app with fvm flutter build apk --debug again.

@romtsn found the reason. In the latest commit from Oct 1st, they included the x86 platform by default for debug builds.

Appending --target-platform=android-64 will resolve this error.

I also left a comment on the Flutter PR asking the developer if this decision was intentional or by accident.

As written here, we should further investigate and check our gradle config for potential errors.
