+Relative lib imports should be avoided.
+
+== Why is this an issue?
+
+The https://dart.dev/guides/libraries/create-packages[`lib` directory] of a Dart project is where the main code of the package is stored. Code living directly under the `lib` directory, when not explicitly declared as private with the ``++__++`` name convention, is considered the public API of the package, and can be imported via https://dart.dev/guides/packages#importing-libraries-from-packages[package imports]. 
+
+When importing code from a `lib` directory of a package available in the local file structure, it is recommended to use package imports instead of relative imports. 
+
+This is because relative imports may cause duplicate imports and may lead to confusion.
+
+[source,dart]
+----
+import 'package:my_package/my_module.dart'; // OK
+import '../my_module.dart'; // Noncompliant: duplicate of above
+----
+
+== How to fix it
+
+Convert the relative import to a package import.
+
+=== Code examples
+
+==== Noncompliant code example
