</div>
<n-config-provider :theme="theme">
  <n-card>
    <n-config-consumer
      @theme-change="handleThemeChange"
      v-slot="{ theme }"
    >
      <div>theme: {{ theme }}</div>
    </n-config-consumer>
  </n-card>
</n-config-provider>
```
```js
export default {
  data () {
    return {
      theme: 'dark'
    }
  },
  methods: {

      this.$NMessage.info(theme)
