How to " show Label " float action button?

Runtime error when showing label text in floating button

That’s normal.. Because the FAB needs some time for itself to setup all things. Use the “Show Label” block together with the FAB click event. Then you will see that it works! Fun fact: I created the feature and the error message which you can see for exact this case.
