How to Get File Path from URI working on -- Android Oreo (8.1) or above

FileUtil

fun Uri.toFilePath(context: Context) : String {
    val id = DocumentsContract.getDocumentId(this)
    val inputStream = context.contentResolver.openInputStream(this)

    val file = File(context.cacheDir.absolutePath + "/" + id)
    writeFile(inputStream!!, file)
    return file.absolutePath
}

fun writeFile(`in`: InputStream, file: File?) {
    var out: OutputStream? = null
    try {
        out = FileOutputStream(file)
        val buf = ByteArray(1024)
        var len: Int
        while (`in`.read(buf).also { len = it } > 0) {
            out.write(buf, 0, len)
        }
    } catch (e: Exception) {
        e.printStackTrace()
    } finally {
        try {
            out?.close()
            `in`.close()
        } catch (e: IOException) {
            e.printStackTrace()
        }
    }
}
