Heya
Can you describe this issue in detail? I am good with Flutter and willing to write about it :)

It's there in the todo list. But not at the near top.

Dash already has a flutter docset: flutter/flutter#24374 (merged from https://github.com/imWildCat/flutter-docset) — maybe some of that work can be reused for devdocs?

The docset URL for dash is: https://cdn.jsdelivr.net/gh/imWildCat/flutter-docset@master/flutter.xml <— to add flutter docs in the Dash app go to -> Settings -> Downloads tab -> select
Main Docsets on the left -> click ➕ and enter the URL

Flutter do package the offline API docs for Dash. They have also provided the Docset manifest for both the Stable version and Master version API. They are up to date.
