Flutter dynamic height fire multiple times with 0 value

Question

I'm trying to make a responsive app with dynamic size using "get.dart" to get the height and width of each device. here is the sample code to get the height and width:

Dimensions class:

import 'package:get/get.dart';

class Dimensions {
 static double screenHeight = Get.context!.height;
 static double screenWidth = Get.context!.width;

 static double pageView = screenHeight/2.64;

}

Whenever I print the value from Main Class using this code :

print("Current height is " + Get.context!.height.toString());

sometimes it will return multiple times with 0 as the first one, here the example:

I/flutter (12775): Current height is 0.0 
I/flutter (12775): Current height is 592.0

And because of the first one returns 0, for some reason, all my Containers that use the dynamic size also return 0. is there a way to prevent multiple fires or get the last value to make sure the dynamic size will never be 0?

If I Run from debug it never fires multiple times, but when I try to run using flutter run --release, 50% times when launching the app will always fire multiple time with 0 as the first value
