在flutter中创建一个有状态的小部件时，你可能不希望小部件的某些字段发生变化。在这种情况下，我很难弄清楚是总是从状态的widget引用中引用这些字段更好，还是在状态中声明这些字段更好，然后从小部件中获取任何初始值。例如：

class MyStatefulWidget extends StatefulWidget {
    final bool? mutateMe; // allows the user to provide an initial value of a mutable field
    final bool? doNotMutateMe; // allows the user to provide the value of a field that is not intended to be mutated

    MyStatefulWidget({ super.key, this.mutateMe, this.doNotMutuateMe });

    @override State<MyStatefulWidget> createState() => MyStatefulWidgetState();
}

class MyStatefulWidgetState extends State<MyStatefulWidget> {
    late bool mutateMe;
    late bool doNotMutateMe; // <-- HERE: is it better to include this field here?

    @override void initState() {
        mutateMe = widget.mutateMe ?? true; 
        doNotMutateMe = widget.doNotMutateMe ?? false;
    }

    // ...
}

对于像doNotMutateMe这样的字段，不打算修改，在state对象中重新创建字段是否有意义，并且总是引用widget.doNotMutateMe？我读到state对象比小部件更有效，所以我很好奇这可能有什么含义？
