IsolateBlocProvider<T extends IsolateBlocBase<Object?, State> , State> class
Takes a ValueBuilder
that is responsible for creating the bloc
and
a child which will have access to the bloc
via
IsolateBlocProvider.of(context)
.
It is used as a dependency injection (DI) widget so that a single instance
of a bloc
can be provided to multiple widgets within a subtree.
Automatically handles closing the bloc
when used with create
.
IsolateBlocProvider(
create: (BuildContext context) => BlocA(),
child: ChildA(),
);

IsolateBlocProvider.value({Key? key, required IsolateBlocWrapper<
Object?> value, Widget? child}) -
Takes a
bloc
and a child which will have access to thebloc
viaIsolateBlocProvider.of(context)
. WhenIsolateBlocProvider.value
is used, thebloc
will not be automatically closed. As a result,IsolateBlocProvider.value
should mainly be used for providing existingbloc
s to new routes.
