Passing props dynamically to a component inside a v-for loop - vue.js

Question

I have a v-for loop that iterates through an array of meetings (meetings between sellers and potential buyers of used cars) and prints a card for each meeting, a basic display of who the meeting is with, what car it is about and the scheduled date. Now, I implemented a button that when clicked, opens a dialog with a Google Maps component that shows the marker for the agreed location of the meeting.
My problem is that no matter what card I click on, the dialog will always display the location of the LAST card, regardless of which has been clicked. I would think that since Im calling the component INSIDE the v-for loop it would pass props dynamically for each card, on each iteration, but that does not seem to be the case.
Here is the HTML:
<div
v-for="meeting in meetings"
:key="meeting.did"
class="col-12 col-md-6 col-lg-3 q-pa-md q-mx-xl"
>
<q-card class="my-card homeCard q-pa-md">
<q-dialog class="mapDialog flex column" v-model="mapDialog">
<MeetMapComponent
:key="componentKey"
:mapDiv="mapDiv"
:mapData="meeting.address"
:buyerName="meeting.name"
/>
</q-dialog>
<q-card-section
class="tipCardImage flex row justify-end"
:style="`background-image: url(${meeting.car.carImg})`"
>
<router-link
:to="`/user/meet/edit/${meeting.did}`"
style="text-decoration: none"
>
<q-icon
#click="fetchMeeting(meeting.did)"
name="fa-solid fa-pencil editNameIcon q-mb-sm q-ml-sm"
></q-icon>
</router-link>
<q-icon
name="fa-solid fa-trash editNameIcon q-mb-sm q-ml-sm"
#click="triggerDelete(meeting.did)"
></q-icon>
</q-card-section>
<q-card-section>
<div class="cardTitle">
<span>Encuentro Con</span> {{ truncateString(meeting.name, 30) }}
</div>
<div class="tipCardText">
<span>Agendado para el </span>
<p>{{ truncateString(meeting.date, 120) }}</p>
</div>
<div class="flex row justify-end">
<q-btn
#click="mapDialog = true"
class="text-white cardButton"
:class="{ cardButtonMobile: $q.screen.lt.md }"
>Ver Ubicación</q-btn
>
</div>
</q-card-section>
</q-card>
</div>
And here is the code for the MeetMapComponent:
<template>
<div class="meetMapContainer">
<div ref="mapDiv" style="width: 100%; height: 500px" />
<h5 class="text-center text-white">{{ props.mapData.address }}</h5>
</div>
</template>
<script setup>
import { ref } from "vue";
import { useAuthStore } from "stores/auth";
import { storeToRefs } from "pinia";
import { Loader } from "#googlemaps/js-api-loader";
const props = defineProps({
mapData: Object,
buyerName: String,
});
const GOOGLE_MAPS_API_KEY = "...";
const loader = new Loader({ apiKey: GOOGLE_MAPS_API_KEY });
const mapDiv = ref(null);
async function mapRender() {
await loader.load();
const map = new google.maps.Map(mapDiv.value, {
mapTypeId: "roadmap",
center: props.mapData.coordinates,
zoom: 13,
});
console.log(map);
new google.maps.Marker({
position: props.mapData.coordinates,
map,
title: `Encuentro con ${props.buyerName}`,
});
}
mapRender();
</script>

I will help you as much as I understand. You use the mapDialog variable to open the dialogue. But even if this variable is used in v-for, its reference does not change. For this reason, when you want to open a modal, all modals may be opened and the last one may appear because it is the last one opened. Please check the dom.
I think this method can solve the problem.
in script
const meetings = [
{
did: 'some value',
address: 'some address',
name: 'some name',
// add modal flag
showMapModal: false
}
]
template
<div
v-for="meeting in meetings"
:key="meeting.did"
class="col-12 col-md-6 col-lg-3 q-pa-md q-mx-xl"
>
<q-card class="my-card homeCard q-pa-md">
<q-dialog class="mapDialog flex column" v-model="meeting.showMapModal">
<MeetMapComponent
:key="componentKey"
:mapDiv="mapDiv"
:mapData="meeting.address"
:buyerName="meeting.name"
/>
</q-dialog>
</q-card>
</div>
