Properties
-
builder
→ Widget Function(BuildContext context, ReactiveModel<
T> model) -
Widget to display if all the observed ReactiveModels has data or as the default case if any
of the onIdle, onWaiting or onError is not defined
final
-
didUpdateWidget
→ (void Function(BuildContext, ReactiveModel<
T> , WhenRebuilderOr<T> )?) -
Called whenever the widget configuration changes.
final
-
dispose
→ (void Function(BuildContext, ReactiveModel<
T> )?) -
StateBuilderOr( dispose:(BuildContext context, ReactiveModel model) { myModel.dispose([context, model]); }, observe:()=> myModel1, onWaiting: ()=> ... onError: (error)=> ... builder: (context, reactiveModel)=> ... )final - hashCode → int
-
The hash code for this object.
no setterinherited
-
initState
→ (void Function(BuildContext, ReactiveModel<
T> )?) -
WhenRebuilderOr( initState:(BuildContext context, ReactiveModel model)=> myModel.init([context,model]), observe:()=> myModel1, onWaiting: ()=> ... onError: (error)=> ... builder: (context, reactiveModel)=> ... )final - key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
-
observe
→ (ReactiveModel<
T> Function()?) -
an observable class to which you want WhenRebuilder to subscribe.
final
-
observeMany
→ List<
ReactiveModel Function()> ? -
List of observable classes to which you want this WhenRebuilder to subscribe.
final
- onData → (Widget Function(T data)?)
-
Widget to display if all the observed ReactiveModels has data.
final
- onError → (Widget Function(dynamic error)?)
-
Widget to display when the at least on of the observed ReactiveModels has an error.
final
- onIdle → (Widget Function()?)
-
Widget to display when the widget is first rendered and before executing any method.
final
-
onSetState
→ (dynamic Function(BuildContext context, ReactiveModel<
T> model)?) -
Called whenever this widget is notified.
final
- onWaiting → (Widget Function()?)
-
Widget to display when the at least on of the observed ReactiveModels is in the waiting state.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
shouldRebuild
→ (bool Function(ReactiveModel<
T> )?) -
final
-
watch
→ (Object Function(ReactiveModel<
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(
) → _WhenRebuilderOrState< 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
-

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.
