```

設定項目は多いですが、今回通知プラグインを使ってみます。

```
// Quasar plugins
plugins: ['Notify', 'BottomSheet']
```

```Index.vue
<template>
  <div>
    <h3>通知プラグインデモ</h3>
    <q-btn
      @click="$q.notify('１つ目のメッセージ')"
      color="primary"
      label="通知を表示"
    />

    <q-btn
      @click="showNotification"
      color="primary"
      label="ほかの通知を表示"
    />
  </div>
</template>

<script>
export default {
  methods: {
    showNotification () {
      this.$q.notify('ほかのメッセージ')
    }
  }
}
</script>
```
