StatefulBlocWidget class abstract
An abstract base class for creating stateful widgets that use BLoCs.
The StatefulBlocWidget class provides a consistent structure for creating stateful widgets that are powered by BLoCs (Business Logic Components). It encourages separation of concerns and simplifies the process of integrating BLoCs into widgets.
Subclasses of StatefulBlocWidget are expected to provide a bloc
instance
in their corresponding state class. The onBuild
method should also be overridden
in the state class to return the actual widget content based on the provided
BuildContext.
Example usage:
class MyStatefulWidget extends StatefulBlocWidget {
const MyStatefulWidget({Key? key}) : super(key: key);
@override
State<StatefulBlocWidget> createState() => MyStatefulWidgetState();
}
class MyStatefulWidgetState extends State<MyStatefulWidget> {
final MyBloc _bloc = MyBloc();
@override
MyBloc get bloc => _bloc;
@override
Widget onBuild(BuildContext context) {
return // Your widget content here
}
}
