Flutter responsive UI with Getx is not automatically updated

Question

I used Getx to Get the height/width and made a Dimensions class so that dimensions would stay responsive through out the whole app in any device with minimum code

the problem is Get.height and Get.width are static and only get values once at run time so if the user switched to landscape or minimized the tab the UI is not updated accordingly

this is the dimensions class:

import 'package:get/get.dart';

class Dimentions {
   static double screenHight = Get.context!.height;
   static double screenWidth = Get.context!.width;

   //u make a suitable view in pixils then get the page hoght and devide to get the factor
   static double pageView = screenHight/2.64;
   static double pageViewContainer = screenHight/3.84;
   static double pageTextContainer = screenHight/7.03;
//hight
   static double hight10 = screenHight/84.4;
   static double hight15 = screenHight/56.27;
   static double hight20 = screenHight/42.2;
   static double hight45 = screenHight/18.76;
   static double hight30 = screenHight/28.13;
//width
   // ur still using hight maybe u wanna change it later
   static double width10 = screenHight/84.4;
   static double width15 = screenHight/56.27;
   static double width20 = screenHight/42.2;
   static double width30 = screenHight/28.13;
   static double width45 = screenHight/18.76;
//font size
   static double font20= screenHight/42.2;
  static double font26 = screenHight/42.2;
  static double font16 = screenHight/52.75;

   //raduis
   static double radius15= screenHight/56.27;
  static double radius20= screenHight/42.2;
   static double radius30= screenHight/28.13;
   //icon size
   static double iconSize24 = screenHight/35.17;
  static double iconSize16 = screenHight/52.75;

   //listview size
   static double listViewImageSize = screenWidth/3.25;
   static double listViewTextSize = screenWidth/3.9;


   //food details
  static double foodImagesize= screenHight/2.41;


  //bottom hoght
  static double bottomHightBar= screenHight/6.25;

  //splash screen
  static double splashImg= screenHight/3.375;
}

usage example:

SizedBox(
                width: Dimentions.width10,
              ),

i want the screenHight screenWidth to get updated dynamically and the use of MediaQuery.of(context).size.height is not possible since there is no context here nor it will get automatically updated
