Flutter GetX setState

Issue

bool download=false; setState(() {download=true;});download==true?Text("new"):("old");

How to write this code by using get X without stateful widget.

Thank you;

Solution

first define a controller class

class ControllerClass extends GetxController{
 RxBool download == false.obs;
}

in your stateless class you can state a set with two ways

inject a controller first like this

 ControllerClass controller = Get.put(ControllerClass());

First:

    Obx(()=>controller.download.value == true?Text("new"):("old"))

in some function

downloadCondition(){
   controller.download.value == // true or false;

}

Second:

    GetBuilder<ControllerClass>(builder: (controller){ return 
     controller.download.value == true? 
    Text("new"):("old"));}

in some function

downloadCondition(){
   controller.download.value == // true or false;
 controller.update();
}
