generate method
Generates Dart code for an input Dart library.
May create additional outputs through the buildStep
, but the 'primary'
output is Dart code returned through the Future. If there is nothing to
generate for this library may return null, or a Future that resolves to
null or the empty string.
Implementation
FutureOr<String?> generate(LibraryReader library, BuildStep buildStep) =>
null;
