ActionChip class
A material design action chip.
Action chips are a set of options which trigger an action related to primary content. Action chips should appear dynamically and contextually in a UI.
Action chips can be tapped to trigger an action or show progress and confirmation. They cannot be disabled; if the action is not applicable, the chip should not be included in the interface. (This contrasts with buttons, where unavailable choices are usually represented as disabled controls.)
Action chips are displayed after primary content, such as below a card or persistently at the bottom of a screen.
The material button widgets, RaisedButton, FlatButton, and OutlineButton, are an alternative to action chips, which should appear statically and consistently in a UI.
Requires one of its ancestors to be a Material widget.
