On Monday, Google announced that they are rolled out the dark mode on its google docs, sheet, and slider on the android device.
The settings for documents, sheets, and slides will be adjusted automatically if the Android system is configured to use the dark theme.
You can also turn dark mode on or off individually for documents, spreadsheets, and slides. If you do this, each app will always be the theme of your choice, regardless of your Android system settings.
Google Docs, Spreadsheets, and Slides themes consider Android’s system-wide settings and are accessible to most users running Android 10 and later.
Users can also go to Menu> Settings> Themes> Dark and adjust the app theme individually. If you’re using the dark theme, you can always preview your document in the light theme using Other> View in Light Theme.
