Other comments

My App.vue file looks like this:

<template>
  <div id="app">
    <v-app>
      <router-view/>
    </v-app>
  </div>
</template>

and main.ts looks like this:

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import Vuetify from 'vuetify'
import 'vuetify/src/stylus/app.styl'
import 'vuetify/src/styles/main.sass'
import '@mdi/font/css/materialdesignicons.min.css'

Vue.config.productionTip = false

Vue.use(Vuetify, {
  icons: {
    iconfont: 'mdi'
  }
})
new Vue({
  router,
  store,
  render: (h) => h(App),
}).$mount('#app')

PS

This is due to this line: https://github.com/vuetifyjs/vuetify/blob/2c785cc7c5b7731a0b7ecbc7bca7d7cea4b57bca/packages/vuetify/src/components/VApp/VApp.ts#L37 In fact, $vuetify.theme is undefined. just like $vuetify.breakpoints

@chaim0m I have just figured it out. Although, to be fair, this was already answered by @MajesticPotatoe in the first reply to this issue, where it states that you must properly instantiate Vuetify as explained in the Alpha 5 release notes. I did that and it works.

In summary do this:

const vuetifyOptions = { }
Vue.use(Vuetify)

new Vue({
  el: '#app',
  vuetify: new Vuetify(vuetifyOptions)
})

Also, here is a link to a working CodePen https://codepen.io/pbastowski/pen/Rzdqra?editors=1010

We are not accepting bug reports for alpha builds. Your particular issue has to do with not properly bootstrapping you app as laid out in alpha.5 patch notes.
