RxBlocProvider<T extends RxBlocTypeBase> class

Used as a DI widget where an instance of a bloc can be provided to multiple widgets within a subtree. Takes a ValueBuilder that is responsible for creating the bloc and a child which will have access to the bloc via RxBlocProvider.of(context).

Automatically handles disposing of the bloc when used with create and lazily creates the bloc if lazy is not explicitly set to false.

RxBlocProvider(
  create: (BuildContext context) => BlocA(),
  child: ChildA(),
);

Constructors

RxBlocProvider({required Create<T> create, Key? key, Widget? child, bool? lazy})
RxBlocProvider.value({required T value, Key? key, Widget? child}): Takes a bloc and a child which will have access to the bloc via RxBlocProvider.of(context). When RxBlocProvider.value is used, the bloc will not be automatically disposed. As a result, RxBlocProvider.value should mainly be used for providing existing blocs to new routes.
