In Add Dependecies Episode, you added Safe Args Gradle Plugin. Safe Args is strongly recommended for navigating and passing data, because it ensures type-safety.

 v ->
  val action = LoginFragmentDirections.actionWelcomeFromLogin(user, getString(R.string
      .action_logged_in))
  v.findNavController().navigate(action)

v ->
  val action = SignUpFragmentDirections.actionWelcomeFromSignUp(user, getString(R.string
      .action_signed_up))
  v.findNavController().navigate(action)

arguments?.let {
  val safeArgs = WelcomeFragmentArgs.fromBundle(it)
  param1 = safeArgs.param1
  param2 = safeArgs.param2
}
