is there nicer way, to lazy initialize nullable property, without then using !! ?

You can get rid of the

!!

on the fragment:

Copy code

progressDialogFragment?.let {
  if (!it.isAdded) it.show(fragmentManager!!, TAG_PROGRESS_DIALOG)
}

Notice however, that this doesn't throw if the fragment is not initialized (you could add a

?: error("not initialized")

or similar at the end though)
