nextcloud_reminder

A Reminder based on todo.txt synced via nextcloud

Current todos:

make repeat-datatype (like: daily, weekly on mo/th/fr, bi-monthly, etc.)
- define isomorphism for 'repeat:'-meta-tag
add interface for repeat-datatype in addReminder.dart
save/load data to/from disk
adding/removing tasks
respect ordering that was used when starting the app when saving.
add Nextcloud-login for getting a Token
use webdav for synchronizing with Nextcloud using that token
sorting by "next up", "priority"
respect 'color:'-meta-tag (usual formats like "#aabbcc", html-colors like "red")
- use color in rendering todos
make application-settings
- store/load settings
- setting for number of days into the future
- theme
  - light/dark mode
  - color theme by system colors
  - own primary/secondary color theme
fancy pop-animation & sound for the checkbox
