#55 added logout button

[Morvvvv]

Placement of the button in the profile page can be changed. I do not think though, that it belongs into any other screen, as this functionaility would not be used often.

Throwing a UnauthenticatedException results in the wanted behavior, but not sure if this is how we want to keep it.

Closes #55

tbh I don't see the point of a IsLogout flag. We also shouldn't throw an exception in case the behavior is wanted :smile:

I would rather:

• make the logout() function in AuthRepository & RemoteAuthRepository return void instead of User
• make thelogout()function in RemoteAuthRepository return builder: (data) {} instead of User.fromMap...
• simply call await _authRepository.logout() in auth_state without a guard
• and possibly set the state manually to an empty user if !state.hasError

Something like this:

  Future<void> logout() async {
    state = const AsyncLoading();
    await _authRepository.logout();

    if (!state.hasError) {
      state = const AsyncData(
          User(id: "", email: "", username: "", profileImgPath: ""));
    }
  }

You also might like to add ref.listen(authStateProvider, (_, next) => next.showSnackBarOnError(context)); to the build method in profile_screen to show any errors that may appear on logout.

Did it like you suggested and it works perfectly fine :)
