missing_dependency

Missing a dependency on imported package '{0}'.

The analyzer produces this diagnostic when there's a package that has been imported in the source but is not listed as a dependency of the importing package.

The following code produces this diagnostic because the package path is not listed as a dependency, while there is an import statement with package path in the source code of package example:

name: example
dependencies:
  meta: ^1.0.2

Add the missing package path to the dependencies field:

name: example
dependencies:
  meta: ^1.0.2
  path: any
