Get.defaultDialog issue with flutter 3.27 SDK

[saguado69]

After upgrading flutter SDK to version 3.27.1, Get.defaultDialog is not working anymore showing a null value error. I have replaced my defaultDialog with basic dialog shown below and the issue persist. The issue happens in the module code below:

extension_navigation.dart

assert(debugCheckHasMaterialLocalizations(context!));

Exception has occurred.
_TypeError (Null check operator used on a null value)

example code:

Get.defaultDialog(
                  title: "Hello",
                  content: Text("This is a simple dialog box"),
                  confirm: MaterialButton(
                    child: Text("OK"),
                    onPressed: Get.back,
                  ),
                );
