Use dartdoc to generate HTML documentaton for your Dart package.

Note: As of Dart 1.12, dartdoc is shipped with the Dart SDK and replaces the older docgen tool.

If you want to contribute to the dartdoc project, see the contributor docs. This page contains information about using the dartdoc tool.

Installing dartdoc

From the Dart SDK

Download the Dart SDK, version 1.12-dev.5.10 or later. If not already added, add the SDK's bin directory to your PATH.

From pub.dartlang.org

You can install the latest version of dartdoc with pub:

$ pub global activate dartdoc

Note: to ensure that this version is run when you type dartdoc on the command line, make sure that ~/.pub-cache/bin is on your PATH, and before the path to the Dart SDK.

Running dartdoc

Generating docs

Run dartdoc from the root directory of package. For example:

$ dartdoc
Generating documentation for 'server_code_lab' into <path-to-server-code-lab>/server_code_lab/doc/api/

parsing lib/client/piratesapi.dart...
parsing lib/common/messages.dart...
parsing lib/common/utils.dart...
parsing lib/server/piratesapi.dart...
Parsed 4 files in 8.1 seconds.

generating docs for library pirate.messages from messages.dart...
generating docs for library pirate.server from piratesapi.dart...
generating docs for library pirate.utils from utils.dart...
generating docs for library server_code_lab.piratesApi.client from piratesapi.dart...
Documented 4 libraries in 9.6 seconds.

Success! Docs generated into <path-to-server-code-lab>/server_code_lab/doc/api/index.html

By default, the documentation is generated to the doc/api directory as static HTML files.

Viewing docs

You can view the generated docs directly from the file system, but if you want to use the search function, you must load them with an HTTP server.

An easy way to run an HTTP server locally is to use the dhttpd package. For example:

$ pub global activate dhttpd
$ dhttpd --path doc/api

Navigate to http://localhost:8080 in your browser; the search function should now work.

Link structure

dartdoc produces static files with a predictable link structure.

index.html                          # homepage
index.json                          # machine-readable index
library-name/                       # : is turned into a - e.g. dart:core => dart-core
  ClassName-class.html              # "homepage" for a class (and enum)
    ClassName.html                  # constructor
    ClassName.namedConstructor.html # named constructor

File names are case-sensitive.
