Vuetify - how to make pagination?

I arrived here after searching for an error I received trying to implement this pagination in my VueJS project: [Vue warn]: Invalid prop: custom validator check failed for prop "length"..

My problem, and it looks like a problem you may have in your question's example code, was my calculation of length was arriving at a decimal answer. For example, if I had 23 records and a page size of 5, it would return 4.6, giving me the error above. I had to wrap my calculation in a Math.ceil() to arrive at the appropriate value for length.

Hope this helps someone :)

<v-pagination
   v-model="currPage"
   :length="Math.ceil(arr.length / pageSize)"
   :total-visible="6"
></v-pagination>

checkout the docs on the events section. I found the input event to handle new page.

<v-pagination
  v-model="pagination.page"
  :length="pagination.pages"
  @input="next"
></v-pagination>

and my next method:

next (page) {
  api.getBillList(page)
    .then(response => {
      this.bills = response.data.content
      console.log(this.bills)
    })
    .catch(error => {
      console.log(error)
    })
}

COMMENT:
Before you implement pagination, try to see if you really need it in the first place, or you can use alternatives:

**ANSWER:**

You can react on pagination.page change with watcher since pagination.page changes on button click, and then execute your method.

watch: {
    "pagination.page": (newPage) => {
        this.onPageChange(newPage);
    }
}

Or react on component's input event:

<v-pagination
    @input="onPageChange"
></v-pagination>
