Flutter setState vs snapshot - flutter

Question

i would like to know whats the diffrence between using setState and snapshot when fetching apis for example
the way i fetch the apis is like the following
Widget text = Container;
Future<AnyClass> fetch() async{
final response = await http
.get(Uri.parse('https://jsonplaceholder.typicode.com/albums/1'));
var result = AnyClass.fromJson(jsonDecode(response.body));
setState(()=> text = result.title)
}
#override
Widget build(BuildContext context) {
return Contianer(child:text)
}
there is another way which uses the snapshot to featch the data instead of using state like the following
Future<Album> fetchAlbum() async { final response = await http
.get(Uri.parse('https://jsonplaceholder.typicode.com/albums/1'));
return Album.fromJson(jsonDecode(response.body));
} #override void initState() {
super.initState();
futureAlbum = fetchAlbum(); } #override Widget build(BuildContext context) {
return MaterialApp(
title: 'Fetch Data Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
appBar: AppBar(
title: const Text('Fetch Data Example'),
),
body: Center(
child: FutureBuilder<Album>(
future: futureAlbum,
builder: (context, snapshot) {
if (snapshot.hasData) {
return Text(snapshot.data!.title);
} else if (snapshot.hasError) {
return Text('${snapshot.error}');
}
// By default, show a loading spinner.
return const CircularProgressIndicator();
},
),
),
),
); }
so i would like to know what are the diffrence between these two methods. Thanks

Answer 1

None, you can check the FutureBuilder source code to see that is does exactly the same: call setState when it has a response.
The advantage of FutureBuilder are:
Easy handling of the different state (loading, loaded, failure)
You don't have to create a StatefulWidget, which means less line of code
