i am using am using flutter and retrofit with riverpod as a statemanagement but anytime i try to run my code it get uncaught and point to the generated file anytime i use a future provider. code below
final customCategoryFutureProvider =
FutureProvider<List<SubCategory>>((ref) async {
final repo = ref.watch(apiServicesProvider);
return repo
.getCustomSubCategories()
.then((value) => value)
.catchError((Object obj) {
if (obj.runtimeType == DioError) {
final res = (obj as DioError?)?.response;
if (res?.statusCode == 401) {
throw Exception('''
Got error : ${res!.statusCode} ->
${res.statusMessage ?? ''} ->
Please sign in''');
}
throw Exception('''
Got error : ${res!.statusCode} ->
${res.statusMessage ?? ''}''');
}
throw Exception('Got error :Unknown Error $obj');
});
});
or
final customCategoryFutureProvider =
FutureProvider<List<SubCategory>>((ref) async {
final repo = ref.watch(apiServicesProvider);
return repo.getCustomSubCategories();
});
but if i use a state provider and catch the error it get caught. anyone have a idea
class CCNotifier extends StateNotifier<CustomCategoryState> {
CCNotifier(this.api) : super(CustomCategoryState.initial()) {
getCustom();
}
final ApiService api;
Future<void> getCustom() async {
try {
state = state.copyWith(status: CCStatus.loading);
final subCat = await api.getCustomSubCategories();
state = state.copyWith(subCat: subCat, status: CCStatus.loaded);
} on DioError catch (e) {
if (e.response?.statusCode == 401) {
state = state.copyWith(
status: CCStatus.failure,
failure: Exception('''
Got error : ${e.response!.statusCode} ->
${e.response!.statusMessage} ->
Please sign in'''),
);
}
state = state.copyWith(
status: CCStatus.failure,
failure: Exception('''
Got error : ${e.response!.statusCode} ->
${e.response!.statusMessage}'''),
);
} on Exception catch (e) {
state = state.copyWith(
status: CCStatus.failure,
failure: Exception('Got error :Unknown Error $e'),
);
}
}
}
P.S: the error is a 401 unauthorized error which is supposed to be caught.
