ControlledWidgetBuilder<Con extends Controller> class

This is a representation of a widget that is controlled by a Controller and needs to be re-rendered when Controller.refreshUI is triggered.

This was created to optimize the render cycle from a ViewState's widget tree.

When Controller.refreshUI is called, only the ControlledWidgets inside ViewState.view will be re-rendered.

Example:

  class ExamplePage extends View {
    @override
    State<StatefulWidget> createState() => ExampleState();
  }

  class ExampleState extends ViewState<ExamplePage, ExampleController> {
    ExampleState() : super(ExampleController());

    Widget get view {
      return Scaffold(
        key: globalKey,
        body: SingleChildScrollView(
          child: Column(
            children: [
              Text("Uncontrolled title that will not re-render"),
              ControlledWidgetBuilder(
                builder: (context, controller) {
                  // Controlled widget that depends on controllers value
                  return Text(controller.foo);
                }
              )
            ]
          )
        )
      )
    }
  }
