Same issue here ═══════ Exception caught by widgets library ═══════════════════════════════════ The following _TypeError was thrown building _FocusInheritedScope: Null check operator used on a null value

The relevant error-causing widget was: Directionality Directionality:file:///Users/mac/.pub-cache/hosted/pub.dev/get-4.6.6/lib/get_navigation/src/root/get_material_app.dart:328:12

When the exception was thrown, this was the stack:

Hello guys, I have same issue in my old projects after spending a lot of time I found two the solutions that you can choose

1. Make sure the initialRoute name is '/' or
2. When the deeplink came from cold start, its always open the '/' as initial route and if your initial route name is not '/', getx throw to the unknown route property so you must set unknownRoute in the GetMaterialApp
   See the code here

   

Hope this help you guys @AbirAppDevs @Sarathlal13
