val HEADER = "Name, DateTime"

var filename = "export.csv"

var path = getExternalFilesDir(null)   //get file directory for this package
//(Android/data/.../files | ... is your app package)

//create fileOut object
var fileOut = File(path, filename)

//delete any file object with path and filename that already exists
fileOut.delete()

//create a new file
fileOut.createNewFile()

//append the header and a newline
fileOut.appendText(HEADER)
fileOut.appendText("\n")
// trying to append some data into csv file
fileOut.appendText("Haider, 12/01/2021")
fileOut.appendText("\n")


val sendIntent = Intent(Intent.ACTION_SEND)
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(fileOut))
sendIntent.type = "text/csv"
startActivity(Intent.createChooser(sendIntent, "SHARE"))

After writing to the file you must close it:
fileWriter.close()
and make this change:
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(qponFile))
