StateBuilder mixin with WidgetsBindingObserver

  • Required parameters:
    • builder : The builder callback to be executed whenever the widget is notified.
    • builderWithChild : The builder callback to be executed whenever the widget is notified. It must be use with child parameter.
    • child : Widget to be used with builderWithChild. Used for optimization. builder or and only or builderWithChild with child must be defined.
  • Optional parameters:
    • observe : The model to observer.
    • observeMany Callback to be called when the widget is first inserted.
    • dispose : Callback to be called when the widget is removed.
    • didChangeDependencies : Callback to be called when dependencies changed.
    • didUpdateWidget : Callback to be called when the widget updated
    • afterInitialBuild : Callback to be called after the first build of the widget.
    • afterRebuild : Callback to be called after each build.
    • didChangeAppLifecycleState : Called when the system puts the app in the background or returns the app to the foreground.
    • didChangeLocales : Called when the system tells the app that the user's locale has changed. For example, if the user changes the system language settings..
