我写代码有个问题：我有一个州

const [theme, setTheme] = useState({ mode: "LIGHT" });

我想做一个切换功能，通过双击将模式切换到“暗”，然后将“暗”切换到“亮”。2我该怎么写呢？

import { createContext, useContext, useState } from "react";

const DARK = "DARK";

const ThemeContext = createContext();

const ThemeProvider = ({ children }) => {
  const [theme, setTheme] = useState({ mode: "LIGHT" });

  const toggleThemeMode = () => {
    setTheme();
    console.log(theme);
  };

  return (
    <ThemeContext.Provider value={{ theme, toggleThemeMode }}>
      {children}
    </ThemeContext.Provider>
  );
};

const useTheme = () => useContext(ThemeContext);

export { ThemeProvider, useTheme, DARK };
