Data update on Get.back () getx
Problem with updating data when going back.
Transition scheme:
ProfileView -> FollowingPersonalView -> ProfilePublicController -> FollowingPersonalView -> ProfilePublicController -> FollowingPersonalView
When going from ProfilePublicController -> FollowingPersonalView, I somehow managed to make the data update, although I'm not entirely sure I did it right.
But when you go back FollowingPersonalView -> ProfilePublicController -> FollowingPersonalView, the data at the last stage is not updated
Logically, they should be picked up from ProfileView
ProfileController
class ProfileController extends GetxController
with SingleGetTickerProviderMixin {
var isLoading = true.obs;
var countPage = 0.obs;
var profileData = UserModel().obs;
TabController tabController;
@override
void onInit() {
tabController = new TabController(length: 3, vsync: this);
Future.wait([
_apiGetProfile(),
]);
super.onInit();
}
Future _apiGetProfile() async {
try {
isLoading(true);
var profile = await RemoteServices.fetchProfile();
if (profile != null) {
profileData.value = profile;
}
} finally {
isLoading(false);
}
update();
}
@override
void onClose() {
super.onClose();
}
}
ProfileView
class ProfileView extends StatelessWidget {
final _profileController = Get.put(ProfileController());

How do I update the data on Get.back ()?
P.S. Is it possible to completely control the launch of the data retrieval function when opening the FollowingPersonalView page?
