Error when trying to fetch images from an API

This is the api where I want to fetch the images. I copied that url in the request part and when trying to render them on the screen it tells me that it expected a string but it found a dynamic list. I tried a tostring() but I really don't know.

    import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';

class Api extends StatefulWidget {
  var url = Uri.parse("https://dog.ceo/api/breed/hound/images");

  Future<dynamic> getdogs() async {
    final respuesta = await http.get(url);

    if (respuesta.statusCode == 200) {
      //print(jsonDecode(respuesta.body));
      return (jsonDecode(respuesta.body));
    } else {
      print("Error con la respusta");
    }
  }

  //Api({Key? key}) : super(key: key);

  @override
  State<Api> createState() => _ApiState();
}

class _ApiState extends State<Api> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: FutureBuilder(
          future: widget.getdogs(),
          builder: (BuildContext context, AsyncSnapshot snapshot) {
            if (snapshot.hasData) {
              return Column(
                children: [
                  Image.network(snapshot.data["message"]
                  ),
                  //Text("${snapshot.data["status"]}"),
                ],
              );
              
            } else {
              return CircularProgressIndicator();
            }
          },
        ),
      ),
    );
  }
}
