    CameraController? controller;

    // Initialize the CameraController with landscape orientation
    controller = CameraController(
    cameraDescription,
    ResolutionPreset.high, // Choose an appropriate resolution preset
    enableAudio: enableAudio,
    androidUseOpenGL: useOpenGL,
    );

    // UI
    return RotatedBox(
    quarterTurns: 1, // Rotate by 90 degrees clockwise for landscape orientation
    child: CameraPreview(controller!),
    );

    use quarterTurns property to move camera orientation.

    RotatedBox(
    quarterTurns: 1, // Adjust this value as per your needed
    child: Stack(
      children: [
        Positioned.fill(
          child: AspectRatio(
            aspectRatio: controller.value.aspectRatio,
            child: CameraPreview(controller),
          ),
        ),
      ],
    ),
  ),

    RotatedBox(
  quarterTurns: 1, // Rotate preview to landscape
  child: CameraPreview(controller!),
),

    If you need to handle potential orientation changes (e.g., during app backgrounding/foregrounding), consider using the OrientationBuilder widget to adapt UI elements based on the device’s current orientation. However, this might not be strictly necessary if you’ve locked the orientation.

    OrientationBuilder(
  builder: (context, orientation) {
    if (orientation == Orientation.landscape) {
      // Landscape UI
    } else {
      // Handle potential portrait mode (if not locked)
    }
  },
),
