Flutter – why String not get localised?

I use getxcontroller, in it there is a String like this:

class HomeController extends GetxController {
  String testString1 = 'test1'.tr;

  testMethod(){
   String testString2 = 'test2'.tr;
 }
}

After I trigger some localise method:

var locale = Locale('de', 'DE');
Get.updateLocale(locale);

testString2 is fine to be translated into German, but testString1 not works, since I will update value of testString1 in other method, and testString1 should have initial value.

I tried RxString/.obs, but not works, what is the right way to fix this issue?

    When you write

    String testString1 = 'test1'.tr;

    testString1 gets set the moment the controller is created and will never change after, even if you update the locale. What you could do is turn it into a getter so it gets the latest translation everytime it’s accessed like

    String get testString1 => 'test1'.tr;
