not entering name in the name field

I tried not entering data of any sort in the name field of the app. The app proceeded to the next story line and showed Hello World!. Is it possible to make sure we get a user input before we proceed??

On the listener for the button (or what ever listener event that happens to change to the next screen), do an if statement and check to see if the text field is not blank.

onButtonClick(e -> {

    if(!textField.equals("")) {
        // Go to next Screen
    } else {
        // Tell use that the info is blank. Maybe toast?
    }

});

Hope this helps!
