FloatingActionBubble class

A material design floating action menu button.

A floating action menu button is a circular icon button that hovers over content to promote a primary action with a expanded menu in the application. Floating action buttons are most commonly used in the Scaffold.floatingActionButton field.

Use at most a single floating action menu button per screen. Floating action buttons should be used for positive actions such as "create", "share", or "navigate". (If more than one floating action button is used within a Route, then make sure that each button has a unique heroTag, otherwise an exception will be thrown.)

If the onPressed callback is null, then the button will be disabled and will not react to touch. It is highly discouraged to disable a floating action button as there is no indication to the user that the button is disabled. Consider changing the backgroundColor if disabling the floating action button.
