I have layout in a fragment. The App is crashing with the error log NullException cannot cast to BarcosdeCapture. For activity is working fine but for fragment it is crashing

I had the same problem. I solved doing this:

private val barcodeCapture by lazy { activity?.supportFragmentManager?.findFragmentById(R.id.qr_code_reader) as? BarcodeCapture }

override fun onCreateView(){
....
  barcodeCapture?.setRetrieval(this@MyFragment)
}
