StatefulComponent class abstract

Base class for components that own local state or lifecycle resources.

Use this for pages, controllers, sockets, subscriptions, text editing controllers, and other local state. A stateful component keeps its fields when it calls setState itself. When its parent rebuilds, Flint creates a fresh child instance by default so constructor values cannot go stale.
