Flags a part of directive that names its library instead of using a string URI.

A part of my.library.name; directive identifies the enclosing library by its declared name, which forces the parent to carry a library name and couples the part to it indirectly. The URI form, part of 'parent.dart';, points straight at the containing file, is more robust, and is the form modern Dart tooling prefers. The rule reports only the named form (a non-empty dotted name with no string URI).

Invalid

example.dartdart
part of foo;
Use a string to refer to the containing library in a part-of directive.
1part of foo;

Valid

example.dartdart
part of 'main.dart';
