Google introduced an official dark theme with Chrome version 74 as an experimental feature (see original post below), but it is official now with version 78. It will flip the Chrome settings, menu, and home page to the dark theme. Other elements and webpages won’t shift to dark mode, as it may break some webpages.
To enable dark mode in Google Chrome, open the browser > tap on the menu (three vertical dots bottom right of the window) > tap on Settings > tap on Themes > and turn on Dark. Your browser will instantly switch to dark mode.
