        PDFView(context = context, set = null).apply {
            Timber.i(File(dashboardViewModel.pdfUri.value).toUri().toString())
            fromUri(File(dashboardViewModel.pdfUri.value).toUri())
                .load()
        }
    })
}

Answer 1

It was not working so i made an new activity in which i use xml instead of composables.

To render pdf i am using Android PdfViewer library.

PdfActivity.kt

class PdfActivity : AppCompatActivity() {

private lateinit var fileName: String
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_pdf)

    val pdfLayout = findViewById<PDFView>(R.id.pdfViewLayout)
    val intent = intent

    if (intent.extras != null) {
        fileName = intent.extras?.getString("fileName").toString()
    }

    try {
        pdfLayout.fromUri(File("${applicationContext.getExternalFilesDir(null)}/$fileName.pdf").toUri())
            .autoSpacing(true)
            .fitEachPage(true)
            .load()
    } catch (e: Exception) {
        Timber.d(e.message)
    }
}
}

activity_pdf.xml
