            .withPermission(Manifest.permission.CAMERA)
            .withListener(object : PermissionListener {
                override fun onPermissionGranted(response: PermissionGrantedResponse) {
                }

                override fun onPermissionDenied(response: PermissionDeniedResponse) {
                }

                override fun onPermissionRationaleShouldBeShown(
                    permission: com.karumi.dexter.listener.PermissionRequest,
                    token: PermissionToken

Research direction

Investigate the Dexter library's permission checking flow, particularly how it handles missing permissions in AndroidManifest.xml. The expected behavior is to provide a clear error message when a permission is requested but not declared. Look at the error handling in the library's core classes (e.g., Dexter.java, PermissionManager.java) and add a check that throws or logs a meaningful message before proceeding. No linked PRs or comments exist, so this issue is open for implementation.
