Dart Class Diagram Generator #
A small command line utility to generate a class (UML or similar) diagram from a Dart package.
Below is a UML diagram of the dcdg source code, created with dcdg. You can find the PlantUML source
Install from pub:
pub global activate dcdg
Install from clone:
pub global activate -s path .
From inside a Dart package repository:
pub global run dcdg
This will dump a PlantUML file to stdout. You can save it to a file instead with the
--help for more options, including ways to filter what ends up in the output. You can find the
help contents in USAGE.txt as well.
Pull requests are welcome! It is intended to be reasonably straightforward to add a new output
format. Take a look at the DOT format implementation in
lib/src/builders for an example.
If you have found a bug or have a feature request please open an issue.
Format code using the
tool/format.sh script. It will have a non-zero exit code if
the formatting changed. That's fine, it does that so it can be used in CI. Run the full
test suite (including unit and functional tests) with
tool/check.sh. If you change
the user interface or add features you should run
tool/docs.sh to regenerate automated
documentation and other resources. This script requires PlantUML.
