While using vuetify, I tried to change the theme from the vuex store using the $vuetify instance, but encountered the following error:
Cannot set property 'theme' of undefinedBelow is the code snippet:
export default {
getters: {},
mutations: {
toggleDarkTheme(state) {
this.$vuetify.theme.primary = "#424242";
}
}
};
To implement the dark theme in Vuetify 2.0, you can follow this approach. (Make sure to refer to the Upgrade guide for themes when upgrading to Vuetify 2.0)
import Vuetify from './plugins/vuetify'
export default {
getters: {},
mutations: {
toggleDarkTheme(state) {
Vuetify.framework.theme.themes.light.primary = "#424242";
}
}
The $vuetify is a special instance property in Vue that allows you to access various Vue instance properties easily.
Vue.prototype.$prop
In your scenario:
import Vue from 'vue';
export default {
getters: {},
mutations: {
toggleDarkTheme(state) {
Vue.prototype.$vuetify.theme.primary = "#424242";
}
}
};
This solution did the trick for me
...
toggleDarkTheme(state) {
window.$nuxt.$root.$vuetify.theme.dark = true
}
When working on Nuxt.js projects that utilize Vuetify as a buildModule, you have the ability to retrieve the $vuetify object through the $nuxt property within the Vue instance:
import Vue from 'vue';
export actions = {
yourAction() {
Vue.prototype.$nuxt.$vuetify.theme.dark = true;
}
}
