Updating state in flutter - flutter

Question

I have a dialog box that sorts a list on my home screen. When I press update the list will sort properly.
What I need to do is run setState for the entire home screen so that the other widgets will reflect the change for the sort order.
Specifically, I have two widgets that I need to rebuild when the update button is pressed.
I have tried to pass a function from the button to the home screen in the constructor and created a function to setState but that didn't work.
Please let me know if I'm being clear enough. Thanks
