This property has no effect on single line FlexLayout items.

The components in the example are added from the code for better showcase purposes. To learn more about the subject you can refer to:

Adding Component From Code

As a best practice, Smartface recommends using the WYSIWYG editor in order to add components and styles to your page or library. To learn how to use UI Editor better, please refer to this documentation

import FlexLayout from "@smartface/native/ui/flexlayout";
import Label from "@smartface/native/ui/label";
