void return type issues #21

Open connelevalsam opened 3 years ago

connelevalsam commented 3 years ago

Lesson 11:


  void toggleView(){
    //print(showSignIn.toString());
    setState(() => showSignIn = !showSignIn);
  }

  @override
  Widget build(BuildContext context) {
    if (showSignIn) {
      return SignIn(toggleView:  toggleView);
    } else {
      return Register(toggleView:  toggleView);
    }
  }```

throws error: this expression has a type of void so it's value can't be used parameter type function

what does the "toggleView" property of SignIn widget accept? My doubt is that because the toggleView() method does not return anything, you can't assign "nothing" to a property of a widget
