The dart doc command (previously called dartdoc)
creates API reference documentation
from Dart source code.
You can add descriptions to the generated documentation
by using documentation comments,
which can contain Markdown formatting.
For guidance on writing doc comments,
see the documentation part of Effective Dart.
Run dart doc from the root directory of your package.
For example:
$ cd my_app
$ dart pub get
$ dart doc .
Documenting my_app...
...
Success! Docs generated into /Users/me/projects/my_app/doc/api
By default,
the documentation files are static HTML files,
placed in the doc/api directory.
You can create the files in a different directory
with the --output flag.
For information on command-line options,
use the help command:
$ dart help doc
