unnecessary_library_name
Library names are not necessary.
Description
#
The analyzer produces this diagnostic when a library directive specifies
a name.
Example
#
The following code produces this diagnostic because the library
directive includes a name:
dart
library some.name;
class C {}
Common fixes
#Remove the name from the library directive:
dart
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.
