on 'flutter run' in Android Studio

build on Linux

To Reproduce Follow steps on here: https://pub.dev/packages/flutter_unity_widget#steps

Expected behavior Start the app.

Unity (please complete the following information):

OS: Linux
Version 2022.2.0

Smartphone (please complete the following information):

Device: Galaxy TapS8 Ultra
OS: Android
Version 13

Additional context flutter version is 3.0.0 and I have followed until "optional manual android setup No6". I have checked my

MinimumSDKVersion, TargetSdkVersion it seems no wrong.
libUnityARCore.so and libarpresto_api.so exists

And read https://github.com/juicycleff/flutter-unity-view-widget/issues/662 . but it doesn't help.
