See Android in particular Android#Flutter as an example of building for it and an Android target.

  • In order to know the UUID of your file, being ePub, PDF or notes you can use ssh remarkable1 then on the device : for X in `ls *metadata`; do test "`grep -i Quick $X`" && echo $X; done
    • You can replace Quick by any string you can expect to be in the filename.
  • ~/xochitl-data is a symbolic link pointing to .local/share/remarkable/xochitl/

    • cd ~/Downloads/remarkable_tosend/ && iwatch -c '~/bin/rmapi put ~/Downloads/remarkable_tosend/%f' -e create . -d
    • alternatively using https://github.com/reHackable/scripts/wiki/repush.sh but requiring the device to accessible, either WiFi or USB

Random findings

• the first "Quick sheet" found (how? modification date?) has special properties, e.g. can't be deleted, others do not
• the modification data applies only to annotations, not changing page
• thumbnails are automatically generated for notebooks and annotated pages of ePub and PDF
  • there is no thumbnail of non annotated ePub or PDF
• uuid as filename or directory is optional, it's possible to use a human readible format
  • name collisions are then not possible, e.g. you can't have 2 "Quick sheet" documents

My notes on Tools gather what I know or want to know. Consequently they are not and will never be complete references. For this, official manuals and online communities provide much better answers.
