FIRE is a static field of Canvas, you need to refer to it in your code as Canvas.FIRE.
From the API for CustomItem:
Key event methods are passed the keyCode indicating the key on which the event occurred. Implementations must provide means for the user to generate events with key codes Canvas.KEY_NUM0 through Canvas.KEY_NUM9, Canvas.KEY_STAR, and Canvas.KEY_POUND. Implementations may also deliver key events for other keys, include device-specific keys. The set of keys available to a CustomItem may differ depending upon whether commands have been added to it.
Support for detection of the FIRE key is not mandated.
