Login.vue

<script setup>
import { useLayout } from '@/layout/composables/layout';
import { ref, computed } from 'vue';
import AppConfig from '@/layout/AppConfig.vue';
import { decodeCredential } from 'vue3-google-login'
import {auth} from '../../../store/modules/auth.module';
import { useStore } from "vuex";
const store = useStore()
const { layoutConfig, contextPath } = useLayout();
const email = ref('');
const password = ref('');
const checked = ref(false);

const logoUrl = computed(() => {
    return `${contextPath}layout/images/${layoutConfig.darkTheme.value ? 'logo-white' : 'logo-dark'}.svg`;
});


const callback = (response) => {
  const userData = decodeCredential(response.credential);
//   const authStore = auth;
//   console.log(authStore.login());
  if (userData.email=='****@gmail.com') {
    return store.dispatch('login')
