How to use the vuetify.version function in vuetify

export async function createApp ({
  start = () => {},
} = {}, ssrContext) {
  // create store and router instances
  const store = createStore()
  const router = createRouter()
  const i18n = createI18n(ssrContext, router)
  const vuetify = createVuetify(ssrContext)

  store.state.app.currentVersion = Vuetify.version

  // sync the router with the vuex store.
  // this registers `store.state.route`
  sync(store, router)

  // create the app instance.
  // here we inject the router, store and ssr context to all child components,
  // making them available everywhere as `this.$router` and `this.$store`.
  const app = new Vue({
    router,
    store,
    ssrContext,
    i18n,
    vuetify,
    render: h => h(App),
  })

export function createApp (ssrContext) {
  // create store and router instances
  const store = createStore()
  const router = createRouter(store)
  const i18n = createI18n(ssrContext)

  store.state.app.currentVersion = Vuetify.version
  store.state.translation.isTranslating = typeof process.env.TRANSLATE !== 'undefined'

  // sync the router with the vuex store.
  // this registers `store.state.route`
  sync(store, router)

  // create the app instance.
  // here we inject the router, store and ssr context to all child components,
  // making them available everywhere as `this.$router` and `this.$store`.
  const app = new Vue({
    router,
    store,
    ssrContext,
    i18n,
    mounted () {
      window.axios = axios
