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. [...]
@nonVirtual, read-only, inherited
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. [...]
final, inherited
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.
read-only, inherited
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
