dependency_validator 4.0.0

Checks for missing, under-promoted, over-promoted, and unused dependencies.

Dependency Validator

A tool to help you find missing, under-promoted, over-promoted, and unused dependencies.

Installation

Add the following to your pubspec.yaml:

dev_dependencies:
  dependency_validator: ^3.0.0

Usage

dart 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 pubspec.yaml
• 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 pubspec.yaml.

Configuration

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

# Set true if you allow pinned packages in your project.
allow_pins: true
# 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 publish warns about unrecognized keys.
