I am using the following code which I want when clicking the ‘OK’ button in the ‘You have internet’ alert dialog, to refresh (reload) the page (Scaffold).

The problem with this code is that when I click OK, the page becomes grey instead of refreshing (reloading). How can I achieve what I want to do? What do I need to change in my code?
