shared image file in Kotlin android studio

I have an application in which I try to share a photo, but when you share the application it crashes.

    val bitmap = (imageViewx1.drawable as BitmapDrawable).bitmap
    val nombreArchivo:String="Shared.jpg"
    val patchload= getExternalFilesDir(Environment.DIRECTORY_PICTURES).toString() + nombreArchivo
    val mifile2 =File(patchload)
    val stream: OutputStream = FileOutputStream(mifile2)
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream)
    stream.flush()
    stream.close()
    val shareIntent = Intent(Intent.ACTION_SEND)
    shareIntent.type = "image/jpg"
    val photoFile = File(filesDir, "PicturesShared.jpg")
    Toast.makeText(this, photoFile.toString(), Toast.LENGTH_SHORT).show()
    shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(photoFile))
    startActivity(Intent.createChooser(shareIntent, "Share image using"))

log:

The exception raised is

android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/app.xxxx.appimage/files/PicturesShared.jpg expobeyond app through ClipData.Item.getUri()

FileUriExposedException is caused by

> The exception that is thrown when an application exposes a file:// Uri
> to another app.

When targeting Api 24 or higher you need to use a content provider to share a file with another app.
