abstract class LoginController extends GetxController {
// late TextEditingController phone;
late TextEditingController password;
late TextEditingController username;
LoginData loginData = LoginData(Get.find());
late StatusRequiest statusRequiest;
bool isShowPassword = true;
GlobalKey<FormState> formstate = GlobalKey<FormState>();
toSignUp();
toForgetPassword();
login();
showPassword() {
isShowPassword = isShowPassword == true ? false : true;
update();
}
}
class LoginControllerImp extends LoginController {
#override
login() async {
var formdata = formstate.currentState;
if (formdata!.validate()) {
statusRequiest = StatusRequiest.loading;
var response = await loginData.postdata(username.text,password.text); //getData from "Data folder" not "controller folder"
// if (kDebugMode) {
// print("===================== $response");
// }
statusRequiest = handlingData(response);
if (StatusRequiest.success == statusRequiest) {
if (response["status"] == "success") {
// data.addAll(response['data']);
Get.offAllNamed(AppRoutes.navbar);
// print(response);
} else {
Get.defaultDialog(title: "99".tr, middleText: "110".tr);

2- json :
class UserModel {
String? userId;
String? userName;
String? userImage;
String? userCreate;
UserModel({
this.userId,
this.userName,
this.userImage,
this.userCreate,
});
UserModel.fromJson(Map<String, dynamic> json) {
userId = json['user_id'];
userName = json['user_name'];
userImage = json['user_image'];
userCreate = json['user_create'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = <String, dynamic>{};
data['user_id'] = userId;
data['user_name'] = userName;
data['user_image'] = userImage;
data['user_create'] = userCreate;
return data;
}
}
3-
class LoginData {
Crud crud;
LoginData(this.crud);
postdata(String username, String password) async {
var response = await crud.postData(AppLink.login, {
"username": username,
// "phone": phone,
"password": password,
});
return response.fold((l) => l, (r) => r);
}
}
4-profile controller
abstract class ProfileController extends GetxController {
initialData();
getdata();
// goToItems(List categories, int selectedCat, String categoryid);
// goToDetails(List items, int selecteditems, String itemsid);
}
class ProfileControllerImp extends ProfileController {
MyServices myServices = Get.find();
String? username;
// String? email;
String? id;
ProfileData homeData = ProfileData(Get.find());
List users=[];
late StatusRequiest statusRequiest;
#override
initialData() {
username = myServices.sharedPreferences.getString("username");
id = myServices.sharedPreferences.getString("id");
}
#override
void onInit() {
getdata();
initialData();
super.onInit();
}
#override
getdata() async {
statusRequiest = StatusRequiest.loading;
var response = await homeData.getData(); //getData from "Data folder" not "controller folder"
statusRequiest = handlingData(response);
if (StatusRequiest.success == statusRequiest) {
// SharedPreferences sharedPreferences = SharedPreferences;
if (response['status'] == "success") {
users.addAll(response['users']);
print(users);
// items.addAll(response['items']);
if (kDebugMode) {
print(response);
}
} else {
statusRequiest = StatusRequiest.faliure;
}
}
update();
}
}
5-profile page
class Profile extends GetView<ProfileControllerImp> {
final UserModel? usermodel;
const Profile({super.key, this.usermodel});
#override
Widget build(BuildContext context) {
Get.put(ProfileControllerImp());
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.white,
// automaticallyImplyLeading: false,
title: Text(
// '${usermodel?.userName}',
'118'.tr,
style: const TextStyle(color: Colors.black),

shrinkWrap: true,
scrollDirection: Axis.horizontal,
itemCount:2,
itemBuilder: (context, index) {
return SingleChildScrollView(

anyone can help plz
in php website and html i used to use $_session['username'] but here in flutter i dont know how to save in seesion , if you can solve this problem in same way plz help and thnx

Answer 1

use your user model, as i can see you areastoraging the data of the user in a class called User so you can use this same class to acces that data in the profile controller in the line
users.addAll(response['users']);
you create a list of user so you have to acces to the index of the list that contains the data of the user and instead of $_sesion["username"] you can use .username for example if you wanna show the data of the first user of the list you can do this:
users[0].name;
and thats equivalent to: $_sesion["username"]
