invalid_dependency

Publishable packages can't have '{0}' dependencies.

The analyzer produces this diagnostic when a publishable package includes a package in the dependencies list of its pubspec.yaml file that isn't a pub-hosted dependency.

To learn more about the different types of dependency sources, check out Package dependencies.

The following code produces this diagnostic because the dependency on the package transmogrify isn't a pub-hosted dependency.

name: example
dependencies:
  transmogrify:
    path: ../transmogrify

If you want to publish the package to pub.dev, then change the dependency to a hosted package that is published on pub.dev.

If the package isn't intended to be published on pub.dev, then add a publish_to: none entry to its pubspec.yaml file to mark it as not intended to be published:

name: example
publish_to: none
dependencies:
  transmogrify:
    path: ../transmogrify
