unnecessary_library_name

Library names are not necessary.

The analyzer produces this diagnostic when a library directive specifies a name.

The following code produces this diagnostic because the library directive includes a name:

library some.name;
​
class C {}

Remove the name from the library directive:

library;
​
class C {}

If the library has any parts, then any part of declarations that use the library name should be updated to use the URI of the library instead.
