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.

Constructors

RxMultiBlocProvider({Key? key, required List<RxBlocProvider<RxBlocTypeBase>> providers, required Widget child})

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 setter, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

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 setter, inherited

Methods

build(BuildContext context) → Widget

Describes the part of the user interface represented by this widget.

override

createElement() → StatelessElement

Creates a StatelessElement to manage this widget's location in the tree.

inherited

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
