HomeActivity.kt

private fun btnSendActions(binding: ActivityHomeBinding) {
    if (binding?.editTextUserName?.text?.toString()?.isNotBlank()!!) {
        val intent = Intent(this, WelcomeActivity().javaClass)
        intent.putExtra(EXTRA_PARAM_USER_NAME, binding.editTextUserName.text.toString())
        startActivity(intent)
        return
    }

    val alert = AlertDialog.Builder(this).create()
    alert.setMessage("Please, fill input correctly.")
    alert.setButton(Dialog.BUTTON_POSITIVE, "OK") { _, _ -> alert.dismiss() }
    alert.show()
