Dart by Example: Pub

Pub is the package manager for Dart.

A typical package has this file structure:

  1. cool_package/
  2.   bin/
  3.     ice
  4.   lib/
  5.     sodas.dart
  6.     src/
  7.       pepsi.dart
  8.       coke.dart
  9.   example/
  10.     soda_example.dart
  11.   web/
  12.     cool_app.dart
  13.     index.html
  14.     style.css
  15.   pubspec.yaml
  16.   README.md
  1. # pubspec.yaml
  3. name: cool_package # use separate package names with underscores
  4. version: 1.2.3 # use semver
  5. description: >
  6.   A really cool package that allows you to
  7.   reticulate your splines and transmogrify
  8.   your unidirectional dataflow.

  12.   sdk: ">=0.12.0"
  13. documentation: http://docs.coolpackagedartlang.com
  14. dependencies:
  15.   yaml: ^2.1.0
  16.   frappe: ^0.4.0
  17. dev_dependencies:
  18.   test: ^0.12.0
  19. dependency_overrides:
  20.   stream_transformers: 0.2.0
  21.   yaml:
  22.     path: ../yaml

dependency_overrides force all packagesin the dependency graph to use a specific version(since only one version of a package is allowed.)

path: dependencies are convenient if multiple packages are being developed on a local machine.

For details, see pub package layout conventions.
