      final response =
          await http.get(Uri.parse('https://dog.ceo/api/breeds/image/random'));
    
      if (response.statusCode == 200) {
        // If the server did return a 200 OK response,
        // then parse the JSON.
        return Album.fromJson(jsonDecode(response.body));
      } else {
        // If the server did not return a 200 OK response,
        // then throw an exception.
        throw Exception('Failed to load album');
      }
    }

    }
    
    void main() => runApp(MyApp());
    
    class MyApp extends StatefulWidget {
      MyApp({Key? key}) : super(key: key);
    
      @override

      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          title: 'Fetch Data Example',
          theme: ThemeData(
            primarySwatch: Colors.blue,
          ),
          home: Scaffold(
            appBar: AppBar(
              title: Text('Fetch Data Example'),
            ),
            body: Center(
              child: FutureBuilder<Album>(
                future: futureAlbum,
                builder: (context, snapshot) {
                  if (snapshot.hasData) {
                    return Column(
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: [
                        Text(snapshot.data!.status),
                        Image(image: NetworkImage(snapshot.data!.message))
                      ],
                    ); //Text(snapshot.data!.ip);
                  } else if (snapshot.hasError) {
                    return Text("${snapshot.error}");
                  }
    
                  // By default, show a loading spinner.
                  return CircularProgressIndicator();
                },
              ),
            ),
          ),
        );
      }

}


//in this way you can get json data and show it in grid or list view.
