Current user is the previous one when logout and login again

I am trying to resolve this issue, the first time I login in my app, everything is ok, but when I logout and login again, the current user (retrieved from parse) is the previous one. If I call again for the current user in another widget, the current user is the correct one, but not in the beginning.

I think that the logout method is the correct one because, as I explained before, in other widgets later in the app, the current user is the right one.

static Future<void> logOut() async {
    ParseUser currentUser = await ParseUser.currentUser();
    ParseResponse userResponse =
        await ParseUser.getCurrentUserFromServer(currentUser.sessionToken);
    ParseUser user = userResponse.result as ParseUser;
    await user.logout(deleteLocalUserData: true);
  }

This is the login method

Future<ParseResponse> login() async {
    try {
      final Map<String, dynamic> queryParams = <String, String>{
        keyVarUsername: username,
        keyVarPassword: password
      };

      final Uri url = getSanitisedUri(_client, '$keyEndPointLogin',
          queryParams: queryParams);
      _saveChanges();
      final Response response =
          await _client.get(url, headers: <String, String>{
        keyHeaderRevocableSession: '1',
      });

      return await _handleResponse(
          this, response, ParseApiRQ.login, _debug, parseClassName);
    } on Exception catch (e) {
      return handleException(e, ParseApiRQ.login, _debug, parseClassName);
    }
  }

This is the class that appears just after the login is completed and where i try to retrieve the current user, achieving the previous user.

class UserInterfaceAppPage extends StatefulWidget {

  @override
  _UserInterfaceAppPageState createState() => _UserInterfaceAppPageState();
}

class _UserInterfaceAppPageState extends State<UserInterfaceAppPage> {
  int _currentIndex = 0;

  static List<Widget> _widgetOptions = <Widget>[];
  Future<SharedPreferences> pref;
  Future<bool> dishes;

  _UserInterfaceAppPageState() {
    initState();
  }

  @override
  void initState() {
    super.initState();

    dishes = DbHelper.insertDishes();

    Future<User> _currentUser = ParseManager().getActualUser();

This is the getActualUser() method where I retrieve the current user.

Future<User> getActualUser() async {
    ParseUser currentUser = await ParseUser.currentUser();
    ParseResponse userResponse =
        await ParseUser.getCurrentUserFromServer(currentUser.sessionToken);
    ParseUser user = userResponse.result as ParseUser;

    User actualUser = User.fromParse(user);

    return actualUser;
  }

Please, let me know if you need more information of any method or class in my app. I tried so many things, included updating the SDK but i have the latest version and I could not find a similar issue.
