I don't think the toFilePath() should be there. Also, this appears to assume
that Platform.packageRoot returns '' if it's not there, not null.

Maybe just:

var packageRoot = (await Platfrom.packageRoot)?.toFilePath();

+  if (packageRoot == '') packageRoot = null;
 
   setUp(() {
     scheduleTempDir();
   });
 
   test('exclude non-lib code from package docs', () {
     schedule(() {
       var thisScript = Platform.script;
       var thisPath = p.fromUri(thisScript);
       expect(p.basename(thisPath), 'only_lib_content_in_pkg_test.dart');
       expect(p.dirname(thisPath), endsWith('test'));
 
-      var packageRoot = Platform.packageRoot;
-      if (packageRoot == '') packageRoot = null;
-
       var codeDir = p.normalize(p.join(thisPath, '..', '..'));
       expect(FileSystemEntity.isDirectorySync(codeDir), isTrue);
       return dg.docgen(['$codeDir/'], out: p.join(d.defaultRoot, 'docs'),
           packageRoot: packageRoot);
     });
 
     d.dir('docs', [
         d.dir('docgen', [
           d.matcherFile('docgen.json',  isJsonMap)
         ]),
         d.matcherFile('index.json', isJsonMap),
         d.matcherFile('index.txt', hasSortedLines),
         d.matcherFile('library_list.json', isJsonMap),
         d.nothing('test_lib.json'),
         d.nothing('test_lib-bar.json'),
         d.nothing('test_lib-foo.json')
     ]).validate();
 
   });
 }
