/**
* An Interaction represents transient UI state for a component, typically separate from the
* actual 'business' state that a component may control. For example, a button typically fires an
* `onClick` callback when the button is pressed and released, but it will still want to show
* that it is being pressed before this callback is fired. This transient state is represented by
* an Interaction, in this case [Pressed]. Using Interactions allows you to build
* components that respond to these transient, component-owned state changes.
*
* The current interactions present on a given component are typically represented with an
* [InteractionState]. See [InteractionState] for more information on consuming [Interaction]s,
* and associated sample usage.
