How can I click in dashboard2 template table?

Dashboard

When I click a table column, I want to send the contents of that column to the next node, but no message is sent when I set the click event. How can I send the message to the next node?

I want to send "Frozen Yogurt" when I clicked that.

Template code:

<template>
  <v-card
    title="Nutrition"
    flat
  >
    <template v-slot:text>
      <v-text-field
        v-model="search"
        label="Search"
        prepend-inner-icon="mdi-magnify"
        variant="outlined"
        hide-details
        single-line
      ></v-text-field>
    </template>

    <v-data-table
      :headers="headers"
      :items="desserts"
      :search="search"
      @click:row="handleRowClick"

    ></v-data-table>
  </v-card>
</template>
<script>

  export default {
    data () {

As per the docs

this.send(msg)

Wow, thank you. I should have asked you here earlier.

Adding for anyone who may find this later and is not using the Vue properties: there are cases where this.send() won't seem to work when called in a function (the browser console remarks that we're trying to read a property of undefined), but will work in the base context. I was able to get around the issue by defining a variable at the top of the area referencing it, and referencing that variable when I needed to use a function:

let sendRef = this.send;

window.myFunction = function () {
   sendRef({payload: "sent"});
}

Thus will because when you define a function, explitiely using that term, javascript creates a new this scope.

The other way of doing this is:

const vue = this

window.myFunction = function () {
   vue.send({payload: "sent"});
}

Or:

window.myFunction = () => {
   this.send({payload: "sent"});
}
