The Ionic 4 Dark theme is finally here! Save Battery on OLED Screens & deliver a fast, flowing & beautiful user experience that not only looks stunning but is also a pleasure to use. White schemas with black text can not only be damaging to your user's eyes but also can be unwelcoming and not very comfortable, especially at night. This theme is based off original ionic 4 components, with all theme code situated in the projects' variables.scss file, so implementing them in your current project is as easy as overwriting the variables.scss.
