RxMultiBlocProvider class
Merges multiple BlocProvider
widgets into one widget tree.
RxMultiBlocProvider improves the readability and eliminates the need to nest multiple RxBlocProviders.
By using RxMultiBlocProvider we can go from:
RxBlocProvider<BlocA>(
create: (BuildContext context) => BlocA(),
child: RxBlocProvider<BlocB>(
create: (BuildContext context) => BlocB(),
child: RxBlocProvider<BlocC>(
create: (BuildContext context) => BlocC(),
child: ChildA(),
)
)
)
to:
RxMultiBlocProvider(
providers: [
RxBlocProvider<BlocA>(
create: (BuildContext context) => BlocA(),
),
RxBlocProvider<BlocB>(
create: (BuildContext context) => BlocB(),
),
RxBlocProvider<BlocC>(
create: (BuildContext context) => BlocC(),
),
],
child: ChildA(),
)
RxMultiBlocProvider converts the RxBlocProvider list into a tree of nested RxBlocProvider widgets. As a result, the only advantage of using RxMultiBlocProvider is improved readability due to the reduction in nesting and boilerplate.

RxMultiBlocProvider({Key? key, required List<
RxBlocProvider< providers, required Widget child})RxBlocTypeBase> > -
Merges multiple
BlocProvider
widgets into one widget tree.const
Properties
- child → Widget
-
The widget and its descendants which will have access to every
bloc
provided by providers. child will be a direct descendent of the last RxBlocProvider in providers.final - hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
-
providers
→ List<
RxBlocProvider< RxBlocTypeBase> > -
The
RxBlocProvider
list which is converted into a tree ofRxBlocProvider
widgets. The tree ofRxBlocProvider
widgets is created in order meaning the firstRxBlocProvider
will be the top-mostRxBlocProvider
and the lastRxBlocProvider
will be a direct ancestor of child.final - runtimeType → Type
-
A representation of the runtime type of the object.
