The `ARCameraActivity` from the `com.camerakit.camerakit_flutter` package is throwing an error [ java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.tryon_camera_kit/com.camerakit.camerakit_flutter.ARCameraActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.]

Describe the bug The ARCameraActivity from the com.camerakit.camerakit_flutter package is throwing an error when starting, stating "You need to use a Theme.AppCompat theme (or descendant) with this activity." This issue occurs because the activity requires a theme from the Theme.AppCompat family, but the current theme applied to the activity is not compatible.

To Reproduce Steps to reproduce the behavior:

Integrate the com.camerakit.camerakit_flutter package into a Flutter project.
Start the ARCameraActivity from the package.
Observe the error message indicating the incompatible theme.

Expected behavior The ARCameraActivity should start without any theme-related issues.

Additional context

Ensure that the ARCameraActivity is correctly configured to use a compatible theme, such as Theme.AppCompat.
Verify that there are no conflicts with other packages or libraries that may be causing the issue.
Consider providing a workaround or temporary fix if available.
