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.

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 of RxBlocProvider widgets. The tree of RxBlocProvider widgets is created in order meaning the first RxBlocProvider will be the top-most RxBlocProvider and the last RxBlocProvider will be a direct ancestor of child.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
