navigatorKey: Get.key Causes "GetRoot is not part of the tree" Exception in GetMaterialApp

[wheadali]

When setting navigatorKey: Get.key inside GetMaterialApp, the following exception occurs at runtime:
'''
Exception: GetRoot is not part of the tree
The relevant error-causing widget was: Builder(dirty)
'''
This issue disappears when navigatorKey: Get.key is removed. It seems that Get.key is not initialized correctly before being used in GetMaterialApp, leading to a navigation-related failure.

Steps to Reproduce:
Use navigatorKey: Get.key in GetMaterialApp.
Run the app.
The exception occurs immediately.
Expected Behavior:
navigatorKey: Get.key should work without causing the exception, ensuring smooth navigation handling.

Environment:
Flutter version: 3.24.3
GetX version:^5.0.0-release-candidate-9.2.1
Dart version: 3.5.3
Device/Platform: Android
Possible Workaround:
Using a manually created GlobalKey instead of Get.key resolves the issue. However, this should not be necessary when using GetX's built-in navigation system.
