When downloading and running the app , you get an error like this:

adb: failed to install D:\DownloadsHDD\arcore_flutter_plugin\example\build\app\outputs\flutter-apk\app-debug.apk: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl1645370067.tmp/base.apk (at Binary XML file line #40): com.difrancescogianmarco.example.MainActivity: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]
Error launching application on sdk gphone64 x86 64.
