use_string_in_part_of_directives
The part-of directive uses a library name.
Description
#The analyzer produces this diagnostic when a part of
directive uses a library name to refer to the library that the part is a part of.
Example
#Given a file named lib.dart
that contains the following:
library lib;
part 'test.dart';
The following code produces this diagnostic because the part of
directive uses the name of the library rather than the URI of the library it's part of:
part of lib;
Common fixes
#Use a URI to reference the library:
part of 'lib.dart';
