Marvel example doesn't handle DioError in the UI

[RobertBrunhage]

Describe what scenario you think is uncovered by the existing examples/articles
In the home.dart file the .when error case doesn't handle DioError, for example doing this:

 if (err is DioError) {
      return Text(err.message);
 }

Describe why existing examples/articles do not cover this case
For now you are doing the following which will just print "Instance of..."

error: (err, stack) {
   return Scaffold(
     appBar: AppBar(title: const Text('Error')),
     body: Center(
       child: Text('$err'),
     )
  );
},
