The CameraManager class has two constants defined MIN_FRAME_WIDTH and MIN_FRAME_HEIGHT. You should modify them as desired and everything should work:

private static final int MIN_FRAME_WIDTH = 240;  // (your desired value here)
private static final int MIN_FRAME_HEIGHT = 240; // (your desired value here)

If you are using ZxingScannerView, you can override createViewFinderView() and increase or decrease the framing rectangle size via viewFinderView like this :

scannerView = object : ZXingScannerView(requireContext()) {
    override fun createViewFinderView(context: Context?): IViewFinder {
         val viewfinderView = super.createViewFinderView(context)
         viewfinderView.setViewFinderOffset(-90) // increase size of framing rectangle
         return viewfinderView;
       }
    }
yourLayour.addView(scannerView)
scannerView.startCamera()
