Visualize package dependencies in your Dart project
Make sure you run pub get or pub upgrade in your target project directory.
Example
Here's an example of pubviz run on itself.
Installing
Activate pubviz.
$ dart pub global activate pubvizUse
If you have configured your PATH correctly, you can run pubviz
directly.
$ pubvizOtherwise, you can use the pub global command.
$ dart pub global run pubvizGenerate and open an html file for the package on the current path.
$ pubviz openShould open your default browser to something like:
Print GraphViz dot format to command line for a package on a specified path.
$ pubviz --format=dot print /path/to/http_packageYou should see output something like:
digraph G {
node [fontname=Helvetica];
edge [fontname=Helvetica, fontcolor=gray];
http [label="http
0.9.2+3",fontsize=18,style=bold,shape=box,margin="0.25,0.15"];
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
1.0.0",shape=box,margin="0.25,0.15",style=bold];
stack_trace [label="stack_trace
0.9.1",shape=box,margin="0.25,0.15",style=bold];
stack_trace -> path [label=">=1.0.0-rc.1 <2.0.0"];
unittest [label="unittest
0.9.3",style=bold];
unittest -> stack_trace [label=">=0.9.0 <0.10.0",color=gray];
}Generate PDF, PNG and other files
GraphViz tool allows dot format to be converted to various types of outputs like PNG, PDF or SVG.
In order to export pubviz data to PNG file you need to install GraphViz package on your machine (see detailed installation instructions).
On macOS:
brew install graphvizOn Windows:
winget install graphvizThen you can save the pubviz output to a file and convert it with dot command to desired output type, e.g.:
pubviz --format=dot print > output.dot
dot -Tpdf output.dot -o output.pdfThe full list of possible output types is available on the GraphViz website.
