var fabOptionEnabled: Boolean
The enabled state of this FabOption and its label. Disabled FabOptions and labels will be visually distinct and unclickable. Default value is true (enabled).
Usage of this property is preferred over the inherited is/setEnabled methods.
NOTE: If you disable a FabOption and its label, remember to re-enable it before trying to update one of its properties. For example, disabling a FabOption then manually changing its background color will not automatically re-enable the FabOption. It, and its label, will remain disabled.
