Calling notifyListeners(); two successive times!

Chapter 7 :arrow_right: Adding the log out capability

In the snippet bellow, doesn’t initializeApp(); notify listeners? why we should call notifyListeners(); again?

void logout() {

    _loggedIn = false;

    _onboardingComplete = false;

    _initialized = false;

    _selectedTab = FooderlichTab.explore;

    initializeApp();

    notifyListeners();

  }

Hi.

This question interests me too.

I think this notifylistener (logout one) is useful to « reset » the state.

Then, we call initializeApp to go back to the loading (2sec) and login page.

I wonder if writing the functions in this order is not more understandable and if it’s correct too…

void logout() {

_loggedIn = false;

_onboardingComplete = false;

_initialized = false;

_selectedTab = FooderlichTab.explore;

notifyListeners();

initializeApp();

}

Is it possible to use this code ?

void logout() {

_loggedIn = false;

_onboardingComplete = false;

_initialized = false;

_selectedTab = FooderlichTab.explore;

initializeApp();

}

notifyListeners() will be call only one time with initializeApp().
