How to change bool value without changing the app state or without setState? – Flutter

I have a bool called isSubmited. Default value is false. I want to change the value when user click on a button but the fact is how can I do it without the setState method in flutter.
I just want to change the value not the user interface. I just want change the bool value nothing else. But not the app state itself!

    you can use hive cache so set/get your boolean value ( or any other value bool, String, anytime in your app without changing user interface

    Example :

    var box = Hive.box(‘myBox’);

    box.put(‘isSubmited’, true);

    bool isSubmited = box.get(‘isSubmited’);

    you can update the bool value without setState method.
    if you are not updating the state on the app based on "isSubmited" value then you don’t need to setState. just assign it like this

    onPressed:(){
isSubmitted=true; 
}
