How can I send an item to a dialog in a different VueJS component?

Having multiple smaller components instead of one big component is the goal for my project. Currently, I have a component with a <v-data-table> that displays various items. Each row includes a button that, when clicked, opens a <v-dialog> showing detailed information about the selected item. My challenge lies in figuring out how to pass the selected item from the table to the dialog, especially since they are in separate components.

The Vue code snippet below illustrates how the dialog is opened:

<template v-slot:item.open="{ item }">
                <v-tooltip top>
                    <template v-slot:activator="{ on }">
                        <v-icon size="20px" color="green darken-1" v-on="on" @click="openDialog2(item)">
                            mdi-arrow-expand-all
                        </v-icon>
                    </template>
                    <span>Open</span>
                </v-tooltip>

<v-dialog
                v-if="this.dialog2"
                v-model="fullDialog"
                persistent
                max-width="1200"
        >

Additionally, here is the JavaScript function responsible for passing the item to the dialog (works only when the dialog and <v-data-table> are within the same component):

 openDialog2(item) {
                this.fullDialog = Object.assign({}, item);
                this.dialog2 = true;
            }

Any guidance or suggestions on how to efficiently transfer the item to the dialog in a different component would be highly appreciated. Thank you!

There is a particular method I can choose to handle this situation.

Vuex State management (https://vuex.vuejs.org/)

When considering sharing data among different components, I believe that state management is the most efficient approach. Why not use props and when to use vuex - as you mentioned, many small components may need to access or modify data, making it cumbersome to pass props down to deep levels or different hierarchies. Learn how to integrate vuex into your project by referring to https://vuex.vuejs.org/guide/.

State management serves as the single source of truth, allowing any component to easily access any state. The beauty of it is that when one component modifies the state, all other components utilizing the same state are automatically updated due to Vue reactivity.

When I mention state, I am referring to the item you intend to pass to components.
