Dart Class Diagram Generator

A small command line utility to generate a class (UML or similar) diagram from a Dart package.

Examples

Below is a UML diagram of the dcdg source code, created with dcdg. You can find the PlantUML source in the example/ directory.

Example UML Diagram

Installation

Install from pub:

pub global activate dcdg

Install from clone:

pub global activate -s path .

Usage

From inside a Dart package directory:

pub global run dcdg

This will dump a PlantUML file to stdout. You can save it to a file instead with the -o option.

See --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.

Examples

There are test fixtures in test/fixtures/. Each Dart package in this directory contains various (fake) classes. Try running DCDG against these fixtures to familiarize yourself with how it works.

Contributing

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.

Development

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 documentation and other resources. This script requires PlantUML.
