The official Flutter documentation can be found here.

Flutter – Error: [Get] the improper use of a GetX has been detected. You should only use GetX or Obx for the specific widget that will be updated

There is no heavy widget, that why I am facing this issue:

Code:

 Obx(()=>InkWell(
          onTap: (){
            controller.login();
          },
          child: Container(
            alignment: Alignment.center,
            height: 50,
            width: 150,
            color: Colors.greenAccent,
            child: Text('Login Here'),
          ),
        ),
     ),

I just want to call this function properly, instead it gives me error of improper use of GetX

    the Getx has Obx widget in order that it triggeres updates if that widget uses some observable Rx, if you didn’t use any of it then this error is thrown since it is a waste of resources.

    you will need either to start using an actual observable Rx<T> inside of it if you need it. otherwise if you don’t want to update that widget then you don’t need to wrap it with Obx.

     Obx(()=>InkWell(
          onTap: (){
            controller.login();
          },
          child: Container(
            alignment: Alignment.center,
            height: 50,
            width: 150,
            // If you are using an Obx-wrapped widget, you need a variable created with <Rx> that affects the widget's state. You do not need to use the Obx widget for the controller value accessed within the functions.
            color: controller.someRxBoolValue ? Colors.red : Colors.greenAccent,
            child: Text('Login Here'),
          ),
        ),
