Widget build(BuildContext context) {
 return Scaffold(
   key: key,
   appBar: AppBar(
     title: const Text("Copy"),
     centerTitle: true,
   ),
   body: Column(mainAxisAlignment: MainAxisAlignment.center, children: < Widget>[
     const SelectableText.rich(
       TextSpan(
         children: [
           TextSpan(text: "Copy me", style: TextStyle(color: Colors.red)),
