在Vuex getter中使用组件属性的正确方法是什么？

// 在Vuex store中定义getter
const store = new Vuex.Store({
  state: {
    count: 0
  },
  getters: {
    getCountPlusComponentProp: (state) => (componentProp) => {
      return state.count + componentProp;
    }
  }
});

// 在组件中使用getter
export default {
  computed: {
    countPlusComponentProp() {
      return this.$store.getters.getCountPlusComponentProp(this.componentProp);
    }
  },
  props: {
    componentProp: {
      type: Number,
      default: 0
    }
  }
}
