Flutter state management

A state management can be divided into two categories based on the duration the particular state lasts in an application. Ephemeral − Last for a few seconds like the current state of an animation or a single page like current rating of a product. Flutter supports its through StatefulWidget .

createState method Null safety Creates the mutable state for this widget at a given location in the tree. Subclasses should override this method to return a newly created instance of their associated State subclass: @override State<MyWidget> createState() => _MyWidgetState();

Flutter is declarative. This means that Flutter builds its user interface to reflect the current state of your app: State can be described as “whatever data you need in order to rebuild your UI at any moment in time “.23 Ağu 2021
