How to use @Getter with Parameters

If I have the following getter setup:

const getters: GetterTree<IMyState, any> = {
  // academies: (state, getters) => x.academies,
  academy: (s) => ((id: number) => s.items.find((x) => x.id === id)),
};

How can I use the @Getter decorator in my component to execute my getter based on a vue property:

@Component
export default class MyComponent extends Vue {
  @Prop({required: true})
  public id: number;

  @Getter
  public item
}

I want to bind the id property of my component and use @Getter to retrieve one of a collection of items.

Just call the getter.

@Component
export default class MyComponent extends Vue {
  @Prop({required: true})
  public id: number;

  @Getter
  public item: (id: number) => Item

  created() {
    console.log(this.item(this.id))
  }
}

is done with

getUser: (state: DialogState) => (id: number): UserInfo => {
        for (const userInfo of state.userList) {
            if (userInfo.user_id === id) {
                return userInfo;
            }
        }
        return demoUser;
    },
