A tool to help you find missing, under-promoted, over-promoted, and unused dependencies.
Add the following to your pubspec.yaml:
dev_dependencies: dependency_validator: ^3.0.0
pub run dependency_validator
This will report any missing, under-promoted, over-promoted, and unused dependencies. Any package that either provides an executable or a builder that will be auto-applied via the dart build system will be considered used even if it isn't imported.
- Missing: When a dependency is used in the package but not declared in the
- Under-promoted: When a dependency is used within
lib/but only declared as a dev_dependency.
- Over-promoted: When a dependency is only used outside
lib/but declared as a dependency.
- Unused: When a dependency is not used in the package but declared in the
There may be packages that are intentionally depended on but not used, or there
may be directories that need to be ignored. You can statically configure these
things in a
dart_dependency_validator.yaml file in the root of your package:
# dart_dependency_validator.yaml # Exclude one or more paths from being scanned. Supports glob syntax. exclude: - "app/**" # Ignore one or more packages. ignore: - analyzer
Note: Previously this configuration lived in the
pubspec.yaml, but that option was deprecated because
pub publishwarns about unrecognized keys.
