İnherited widget Flutter example

Why is the build method on State, and not StatefulWidget? Putting a Widget build(BuildContext context) method on State rather than putting a Widget build(BuildContext context, State state) method on StatefulWidget gives developers more flexibility when subclassing StatefulWidget.

To create a stateful widget in a flutter, use the createState() method . The stateful widget is the widget that describes part of a user interface by building a constellation of other widgets that represent a user interface more concretely. A stateful Widget means a widget that has a mutable state.

Ephemeral state (sometimes called UI state or local state) is the state you can neatly contain in a single widget .

In flutter, the inherited widget is a base class that allows those classes to extend the information under the tree from it. Inherited widgets are also a kind of state management technique. It works by telling registered build references when a change occurs .
