| # Third-party Dart packages |
| |
| |
| There are two types of third-party dependencies in the Fuchsia tree: |
| |
| - extracted from [pub][pub]; |
| - sync'd from Git. |
| |
| ## Pub dependencies |
| |
| Pub dependencies are host at [`//third-party/dart-pkg`][dart-3p]. That project |
| is regularly kept up-to-date with [a script][dart-3p-script] that relies on the |
| `pub` tool to resolve versions and fetch sources for the packages that are used |
| in the tree. |
| This script uses a set of canonical local packages which are assumed to be |
| providing the necessary package coverage for the entire tree. |
| |
| Additionally, projects may request third-party dependencies to be imported |
| through the following procedure: |
| |
| 1. create a `dart_dependencies.yaml` file in the project |
| 2. add the desired dependencies in that file: |
| |
| ``` |
| name: my_project |
| dependencies: |
| foo: ^4.0.0 |
| bar: >=0.1.0 |
| ``` |
| |
| 3. add a reference to the file in `//scripts/dart/update_3p_packages.py` |
| 4. run that script |
| 5. merge your changes to `dart_dependencies.yaml` to master |
| 6. merge the files downloaded by running the 'update_3p_packages.py' script, and the script itself, to master. |
| 7. in the '//topaz/manifest/dart' manifest, update the project node 'third_part/dart-pkg' revision attribute with the SHA from your commit in step 6. |
| 8. merge your change to the '//topaz/manifest/dart' manifest file to master. |
