Deps is one of the commands of the pub tool.

$ dart pub deps [--style=<style>] [--[no-]dev] [--executables]

This command prints the dependency graph for a package. The graph includes both the immediate dependenciesImmediate dependencyA dependency that a Dart package directly uses. Learn more that the package uses (as specified in the pubspec), as well as the transitive dependenciesTransitive dependencyA dependency that a package indirectly uses because one of its dependencies requires it. Learn more pulled in by the immediate dependencies.

The dependency information is printed as a tree by default.

For example, the pubspec for the markdown_converter example specifies the following dependencies:

dependencies:
  barback: ^0.15.2
  markdown: ^0.7.2

Here's an example of the dart pub deps output for markdown_converter:

dart pub deps
markdown_converter 0.0.0
|-- barback 0.15.2+6
|   |-- collection 1.1.2
|   |-- path 1.3.6
|   |-- pool 1.1.0
|   |   '-- stack_trace...
|   |-- source_span 1.2.0
|   |   '-- path...
|   '-- stack_trace 1.4.2
|       '-- path...
'-- markdown 0.7.2
