 - GetX is not a bloated. It has a multitude of features that allow you to start programming without worrying about anything, but each of these features are in separate containers, and are only started after use. If you only use State Management, only State Management will be compiled. If you only use routes, nothing from the state management will be compiled. You can compile the benchmark repository, and you will see that using only Get state management, the application compiled with Get has become smaller than all other applications that have only the state management of other packages, because nothing that is not used will be compiled into your code, and each GetX solution was designed to be extra lightweight. The merit here also comes from Flutter's tree shaking which is incredible, and manages to eliminate unused resources like no other framework does.

 And in the UI, when you want to show that value and update the screen whenever tha values changes, simply do this:
 
 ```dart

+Obx(() => Text("${controller.name}"));
