how to avoid multiple find of state in my code ?

[nesteiner]

hey, guys, recently I write this code

class Page extends StatelessWidget {
    GlobalState? _state;
    GlobalState get state => _state!;
    set state(GlobalState value) => _state ??= value;

    Widget build(BuildContext context) {
        state = context.read<GlobalState>();
        return Selector<GlobalState, int>(
           selector: (_, innerState) => innerState.intValue,
           builder: (_, value, child) => ...
        );
    }
}

I think each time the state call notifyListener, the Selector will always looking for the GlobalState in the context again, this is very stupid, how can I fix it ?
