How can I recall a futureprovider (riverpod) on build - flutter

Question

I have a simple page, which shows a product, and i am trying to use riverpod, and futureprovider, but the future is only called the first time i go to the page?
final productInfo = FutureProvider<Map<String, dynamic>>((ref) async {
final response =
await http.get('https://www.api.com/$clickedID');
final content = json.decode(response.body) as Map<String, dynamic>;
return content;
});

Answer 1

With the recent Riverpod, you can do ref.refresh(userProvider) to refresh the provider.

Answer 2

Please use
final userProvider = StreamProvider<User>(
final response =
await http.get('https://www.api.com/$clickedID');
final content = json.decode(response.body) as Map<String, dynamic>;
return content;
);
now you can listen to the provider using watch,
AsyncValue<User> user = watch(userProvider);

Answer 3

No inbuilt functionality, but you can override the value with the same future at a later time.
recallProductInfoFutureProvider() {
final response = http.get('https://www.api.com/$clickedID');
final content = json.decode(response.body) as Map<String, dynamic>;
productInfo.overrideWithValue(content)
}
Consider using with StreamProvider and watching inside Consumer to update UI on overrideWithValue.

Answer 4

There are a two options.
ref.refresh(provider)
ref.invalidate(provider)
Note that if you are using a AsyncValue, the old result will be returned when you refresh the FutureProvider and AsyncValue.isRefreshing will be set to true:
final notificationRepositoryProvider = FutureProvider<bool?>((ref) async {
Future<bool> approveDocument() => Future.delayed(Duration(seconds: 1), () => Future.value(Random().nextBool()));
return approveDocument();
});
class HomeView extends ConsumerStatefulWidget {
const HomeView({Key? key}) : super(key: key);
#override
HomeViewState createState() => HomeViewState();
}
class HomeViewState extends ConsumerState<HomeView> {
#override
Widget build(BuildContext context) {
AsyncValue<bool?> rejectResponse = ref.watch(notificationRepositoryProvider);
return ElevatedButton(
onPressed: () {
// ref.refresh(notificationRepositoryProvider);
ref.watch(notificationRepositoryProvider).;
},
child: rejectResponse.when(
loading: () => const CircularProgressIndicator(
color: Colors.white,
),
skipLoadingOnRefresh: false,
error: (err, stack) => Text('Error'),
data: (data) => Text('Yes: $data'),
));
}
}
