Dracula Dark Mode is designed to be compatible with the Gutenberg block editor. This can be a great way to make the editing experience more comfortable for users, especially for those who spend a lot of time editing and creating content in WordPress.
To display the dark mode switch in the Gutenberg block editor navigate to Dracula > Settings > Dashboard Dark Mode > Enable Block Editor Dark Mode. Now you will notice a switch at the top of your Gutenberg block editor dashboard to enable/ disable dark mode.
