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:


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-o, --[no-]flag-outdated    Check for lasted packages and flag those that are outdated.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


  • Updated output format.

  • And other cleanup...


  • Using nodesep=0.2 on the graph to make it tighter.

  • Hosted code

    • Much more robust handling of node clicks to add/remove.

    • Make it clear that nodes can be clicked by changing the cursor.


  • Better error output if a subprocess fails.

  • Try to handle flutter packages.


  • Better hover-over behavior for outdated dependencies.


  • Update gviz.

  • Support larger dependency graphs.

  • Update version of viz.js.

  • Use viz-lite.js – smaller download.

    • Continue to host vis.js so we don't break existing installations.


  • Use gviz package. Get out of the GraphViz formatting business.


  • Updated dependencies.

  • Fix case where we're pulling in a pre-release version that is after the latest stable version.


  • Send a descriptive user agent to the server.

  • Added retry logic for HTTP requests.

  • Sort the output.


  • Better stack trace on errors.


  • Cleanup, handled some deprecations, improve load time.


  • Tweaks test code, examples, dependencies.


  • Properly escape the latest version for outdated dependencies.

  • Add a reasonable tool-tip for the entire graph.

  • Don't show the root node as outdated.


  • Using CSS animations for effects. Hosting style on GitHub.


  • All fancy with mouse-over effects.


  • Fix


  • With --flag-outdated (-o) do version lookup in parallel. MUCH faster.


  • Allow ignoring packages via --ignore-packages. Thanks, Günter!

  • A fix for running on Windows. Thanks, Oliver!

  • A fix for formatting packages with hyphens. Thanks, Bryon!
