Can anyone share a script similar to "one-click switching theme" for me to learn and reference?

I want to switch the obsidian theme with one click. I feel that the add script should be able to achieve this requirement. Can anyone share a similar script for me to learn and reference? Thanks!

Coming back to this very late - sorry about that. In case you (or anyone searching) still want it:

A QuickAdd macro user script can do this. Create a Macro choice, attach this script as its command, and toggle the command (lightning bolt) on the choice so it's one click away in the command palette or on a hotkey.

module.exports = async (params) => {
	const { app, quickAddApi } = params;
	const customCss = app.customCss;

	const themes = ["", ...Object.keys(customCss.themes ?? {})];
	const picked = await quickAddApi.suggester(
		(theme) => (theme === "" ? "Default" : theme),
		themes
	);

	customCss.setTheme(picked);
};

That opens a suggester over your installed themes (plus the default) and applies the pick. If you'd rather have a strict two-theme toggle in a single click, no prompt:

module.exports = async (params) => {
	const customCss = params.app.customCss;
	customCss.setTheme(customCss.theme === "Minimal" ? "Things" : "Minimal");
};

(Theme names are exactly as shown in Settings -> Appearance.)

One honest caveat: app.customCss is an internal, undocumented Obsidian API. It's widely used in community scripts, but it can change in any Obsidian update, so treat this as a personal script rather than something guaranteed to work forever.

Script basics (params, quickAddApi) are covered here: https://quickadd.obsidian.guide/docs/Advanced/ScriptingGuide

Closing as resolved.
