ResilientContainer class

A general-purpose container that lazily runs an async initializer through a ResiliencePipeline and renders different widgets for each ResilienceStatus.

Use this as a lightweight alternative to ResilientFutureBuilder when you want to wrap an entire screen section (not just a single data value).

Example:

ResilientContainer(
  initializer: () => service.init(),
  child: MyFeatureWidget(),
  loadingChild: const LoadingScreen(),
)

Constructors

ResilientContainer({Key? key, required Widget child, Future<void> initializer()?, Widget? loadingChild, Widget errorBuilder(BuildContext, Object, StackTrace?, VoidCallback retry)?, ResiliencePipelineBuilder pipelineBuilder(ResiliencePipelineBuilder)?})
const

Properties

child → Widget
Widget shown in success (or idle when no initializer is provided).
final
errorBuilder → Widget Function(BuildContext, Object, StackTrace?, VoidCallback retry)?
final
hashCode → int
The hash code for this object.
no setterinherited
initializer → Future<void> Function()?
Async task run on first build. The container enters success state once this completes successfully.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
loadingChild → Widget?
final
pipelineBuilder → ResiliencePipelineBuilder Function(ResiliencePipelineBuilder)?
Optional pipeline customizer.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<ResilientContainer>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void

inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

inherited
toStringShort() → String
