Forward package member in dart

Question

I import a package and would forward a member of it. What syntax does Dart offer for that?

foo.dart

import 'package:xzy/xzy.dart';  // contains class Xyz
// how do I forward Xyz here to make it available in bar.dart?

bar.dart

import 'package:mypackage/foo.dart';
Xyz is hidden here

Answer 1

You can use export

import 'package:xzy/xzy.dart'; 
export 'package:xzy/xzy.dart' show Xyz; 

or just

export 'package:xzy/xzy.dart' show Xyz; 

You don't need to import for that. Just export is enough if you don't need Xyz in this re-exporting file.
