Close dialog when ESC key is pressed

This is the only way I was able to get it to work

mounted() {
    // Close modal with 'esc' key
    document.addEventListener("keydown", (e) => {
        if (e.keyCode == 27) {
            this.$emit('close');
        }
    });
},

Add @keydown.esc="dialog = false" to v-dialog component

<v-dialog v-model="dialog" @keydown.esc="dialog = false"></v-dialog>

data: () => ({
  dialog: false
}),

Additionally, if using dialog as custom component then possibly we need to emit input event:

<template>
  <v-dialog :value="value" @keydown.esc="$emit('input')">
