Je souhaite changer le thème de manière dynamique. J'ai défini lightTheme 和 darkTheme li

export default createVuetify({
  theme: {
    defaultTheme: "lightTheme",
    themes: {
      lightTheme: {
        dark: false,
        colors: {
          primary: "#ad1c3d",
          "page-header-background": "#d7d7ce",
          "page-background": "#cdcdc1",
          "table-header": "#cdcdc1",
          background: "#c0c0b5",
          "header-background": "#b5b5a6",
          "info-text": "#666660",
        },
      },
      darkTheme: {
        dark: true,
        colors: {
          primary: "#52E3C2",
          "page-header-background": "#282831",
          "page-background": "#32323E",
          "table-header": "#2e2e2e",
          background: "#3F3F4A",
          "header-background": "#4a4a59",
          "info-text": "#99999F",
        },
      },
    },
  },
});

Exemples que je peux utiliser this.$vuetify.theme 访问主题，但是我找不到如何在运行时更改主题。 Vuetify 2 中执行此操作的方法有所不同。我找不到任何 Vuetify 3.

Quelle est la bonne façon de changer dynamiquement le thème dans Vuetify 3 ?
