createState method

Builds the state than manages this ViewWidget

This functions is already defined for this ViewWidget class so typically doesn't need to be overridden. An exception is when you need to add a mixin to the state class. To add a mixin, extend ViewState<ViewWidget

class MyWidget extends ViewWidget

 // Overriding createState is only required when adding mixins
 @override
 MyWidgetState createState() => MyWidgetState();

 @override
 Widget build(BuildContext context) {
 // Use `getState` to retrieve your custom ViewState/mixin object
   return getState<MyWidgetState>().buildGreeting(viewModel.message.value);
 }

}

// Extend ViewState and add your mixin class MyWidgetState extends ViewState

mixin MyMixin { buildGreeting(String message) => Text(message); }

class MyWidgetViewModel extends ViewModel { late final message = createProperty
