`class BottomSheetDemo : BottomSheetDialogFragment() {

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    val view = inflater.inflate(R.layout.bottom_sheet,container)
    view.findViewById<Button>(R.id.openButton).setOnClickListener {
        captureScreen()
    }
    return view
}



fun captureScreen(){
    val myActivity = activity ?: return
    val view = myActivity.window.decorView.rootView
    view.isDrawingCacheEnabled = true
    view.buildDrawingCache(true)
    val bitmap = Bitmap.createBitmap(view.drawingCache)
    val file = File(myActivity.cacheDir, "BottomFile.png")
    val fOut = FileOutputStream(file)
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut)
    fOut.flush()
    fOut.close()
}

}`

I tried the code above, but it’s not working. Can anyone provide some guidance?
