One of the three observer widgets in states_rebuilder

const

Properties

afterInitialBuild → (void Function(BuildContext context, ReactiveModel<T>? model)?)

Called after the widget is first inserted in the widget tree.

final

builder → (Widget Function(BuildContext context, ReactiveModel<T>? model)?)

StateBuilder( models:[myModel], builder:(BuildContext context, ReactiveModel model) =>MyWidget(), )

final

builderWithChild → (Widget Function(BuildContext context, ReactiveModel<T>? model, Widget child)?)

StateBuilder( models:[myModel], builderWithChild:(BuildContext context, ReactiveModel model, Widget child) =>MyWidget(child), child : MyChildWidget(), )

final

child → Widget?

The child to be used in builderWithChild.

final

didChangeDependencies → (void Function(BuildContext context, ReactiveModel<T>? model)?)

StateBuilder( didChangeDependencies:(BuildContext context, ReactiveModel model) { //...your code }, models:[myModel], builder:(BuildContext context, ReactiveModel model) =>MyWidget(), )

final

didUpdateWidget → (void Function(BuildContext context, ReactiveModel<T>? model, StateBuilder<T> oldWidget)?)

StateBuilder( didUpdateWidget:(BuildContext context, ReactiveModel model,StateBuilder oldWidget) { myModel.dispose([context, model]); }, models:[myModel], builder:(BuildContext context, ReactiveModel model) =>MyWidget(), )

final

dispose → (void Function(BuildContext context, ReactiveModel<T>? model)?)

StateBuilder( dispose:(BuildContext context, ReactiveModel model) { myModel.dispose([context, model]); }, models:[myModel], builder:(BuildContext context, ReactiveModel model) =>MyWidget(), )

final

hashCode → int

The hash code for this object.

no setter, inherited

initState → (void Function(BuildContext context, ReactiveModel<T>? model)?)

A tag or list of tags you want this StateBuilder to register with.

final

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

observe → (ReactiveModel<T> Function()?)

an observable class to which you want StateBuilder to subscribe.

final

observeMany → List<ReactiveModel Function()>?

List of observable classes to which you want StateBuilder to subscribe.

final

onRebuildState → (void Function(BuildContext context, ReactiveModel<T>? model)?)

Called whenever this widget is notified and after rebuilding the widget.

final

onSetState → (dynamic Function(BuildContext context, ReactiveModel<T>? model)?)

Called whenever this widget is notified.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

shouldRebuild → (bool Function(SnapState<T>? model)?)

Callback to determine whether this StateBuilder will rebuild or not.

final

watch → (Object? Function(SnapState<T>? model)?)

callback to be executed before notifying listeners. It the returned value is the same as the last one, the rebuild process is interrupted.

final

Methods

createElement() → StatefulElement

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

inherited

createState() → State<StateBuilder<T>>

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

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.
