initState in Notifier with async func

[chairulf]

`@riverpod
class TestSchoolNotifier extends _$TestSchoolNotifier {
late GetSchoolsUseCase _getSchoolsUseCase;
late SchoolsRequest _request;
List _cacheSchools = [];
int currentPage = 1;

@OverRide
PaginationState build() {
state = PaginationStateInitial();
init();
return state;
}

void init() async {
state = PaginationStateLoading();
_getSchoolsUseCase = ref.read(getSchoolsUseCaseProvider);
_request = SchoolsRequest(page: currentPage, pageSize: 20);
final getSchools = await _getSchoolsUseCase.execute(_request);
_cacheSchools = getSchools.fold(
(l) {
state = PaginationStateError(l, StackTrace.current);
return [];
},
(r) {
return r;
},
);
state = PaginationStateData(_cacheSchools);
}
}
`
what is the best practice for initialState notifier with async func ?
