API - Multitenancy - Works with Postman only - laravel

Question

When i login through the flutter client, i receive the previous users content.
I assume this is due to an issue in the logout function.
Everything works fine in Postman(Relevant user content is presented in Postman)
lib\providers\auth_provider.dart
import 'package:demo_app/services/api.dart';
import 'package:flutter/material.dart';
class AuthProvider extends ChangeNotifier {
bool isAuthenticated = false;
late String token;
ApiService apiService = ApiService('');
Future<void> register(String name, String email, String password, String passwordConfirm, String deviceName) async{
token = await apiService.register(name, email, password, passwordConfirm, deviceName);
isAuthenticated = true;
notifyListeners();
}
Future<void> logIn(String email, String password, String deviceName) async {
token = await apiService.logIn(email, password, deviceName);
isAuthenticated = true;
notifyListeners();
}
Future<void> logOut() async {
token = '';
isAuthenticated = false;
notifyListeners();
}
}
The api.dart file looks like this
lib\services\api.dart
class ApiService{
late String token;
ApiService(this.token);
final String baseUrl = 'http://flutter-api.test/api/';
Future<List<Category>> fetchCategories() async {
http.Response response =
await http.get(Uri.parse('${baseUrl}categories'),
headers: {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.acceptHeader: 'application/json',
HttpHeaders.authorizationHeader: 'Bearer $token'
},
);
List categories = jsonDecode(response.body);
return categories.map((category) => Category.fromJson(category)).toList();
}
..
..
Future<String> logIn(String email, String password, String deviceName) async {
String uri = '${baseUrl}auth/login';
http.Response response = await http.post(Uri.parse(uri),
headers: {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.acceptHeader: 'application/json',
},
body: jsonEncode({
'email': email,
'password': password,
'device_name': deviceName
})
);
if(response.statusCode == 422){
Map<String, dynamic> body = jsonDecode(response.body);
Map<String, dynamic> errors = body['errors'];
String errorMessage = '';
errors.forEach((key, value){
value.forEach((element){
errorMessage += element + '\n';
});
});
throw Exception(errorMessage);
}
return response.body;
}
}
The category_privder.dart file looks like this
lib\providers\category_provider.dart
import 'package:demo_app/models/category.dart';
import 'package:demo_app/providers/auth_provider.dart';
import 'package:demo_app/services/api.dart';
import 'package:flutter/material.dart';
class CategoryProvider extends ChangeNotifier{
List<Category> categories = [];
late ApiService apiService;
late AuthProvider authProvider;
CategoryProvider(this.authProvider){
apiService = ApiService(authProvider.token);
init();
}
Future init() async{
categories = await apiService.fetchCategories();
notifyListeners();
}
Future<void> addCategory(String name) async{
try{
Category addedCategory = await apiService.addCategory(name);
categories.add(addedCategory);
notifyListeners();
} catch(e){
await authProvider.logOut();
// ignore: avoid_print
// print(e);
}
}
Future<void> updateCategory(Category category) async{
try{
Category updatedCategory = await apiService.updateCategory(category);
int index = categories.indexOf(category);
categories[index] = updatedCategory;
notifyListeners();
} catch(e){
await authProvider.logOut();
}
}
Future<void> deleteCategory(Category category) async{
try{
await apiService.deleteCategory(category.id);
categories.remove(category);
notifyListeners();
} catch(e){
await authProvider.logOut();
}
}
}
I am trying to get the flutter client to display the relevant categories of a particular user. The Laravel part seems to work well, because everything works fine in Postman
Maybe it is something to do with the BuildContext
How can i solve this issue
lib\screens\login.dart
