Support dark mode #1
Description
The Dasher Version Six custom keyboards, for Android and for iOS, and standalone mobile app, for iOS only at time of writing, should support dark mode. This could be based on dark mode support in the projects on which they are based, as follows.
- Dasher Version Six doesn't support dark mode at time of writing but see Support dark mode dasher-web#59
- Captive Web View dark mode support isn't used by the keyboards and app here yet.
