Visualize package dependencies in your Dart project

Build Status Coverage Status

Make sure you run pub get or pub upgrade in your target project directory.


Here's an example of pubviz run on itself.


Activate pubviz.

~/anypath/> pub global activate pubviz


If you have installed Dart v1.7+ and modified your PATH, you can run pubviz directly.

~/proj_path/> pubviz [arguments]

Otherwise you can use the pub global command.

~/proj_path/> pub global run pubviz [arguments]

Generate and open an html file for the package on the current path.

~/http_package/> pubviz open

Should open your default browser to something like:


Print GraphViz dot format to command line for a package on a specified path.

~/any_path/> pubviz --format=dot print /path/to/http_package

You should see output something like:

digraph G {
  node [fontname=Helvetica];
  edge [fontname=Helvetica, fontcolor=gray];

  http [label="http
  http -> path [label=">=0.9.0 <2.0.0",penwidth=2];
  http -> stack_trace [label=">=0.9.1 <0.10.0",penwidth=2];
  http -> unittest [label=">=0.9.0 <0.10.0",penwidth=2,style=dashed];

  path [label="path

  stack_trace [label="stack_trace
  stack_trace -> path [label=">=1.0.0-rc.1 <2.0.0"];

  unittest [label="unittest
  unittest -> stack_trace [label=">=0.9.0 <0.10.0",color=gray];

pubviz with no arguments prints help

usage: pubviz [--format=<format>] (open | print) [<package path>]

  open   Populate a temporary file with the content and open it.
  print  Print the output to stdout.

-f, --format
          [dot]             Generate a GraphViz dot file
          [html]            Wrap the GraphViz dot format in an HTML template which renders it.

-o, --[no-]flag-outdated    Check for lasted packages and flag those that are outdated.

If <package path> is omitted, the current directory is used.
