lightning:utilityBarAPI Example

This component allows you to access methods for programmatically controlling a utility within the utility bar of a Lightning app. The utility bar is a footer that gives users quick access to frequently used tools and components. Each utility is a single-column Lightning page that includes a standard or custom Lightning component.

To access the methods, create an instance of the lightning:utilityBarAPI component inside of your utility and assign an aura:id attribute to it.
