Adding Bottom Navigation Bar

Until now, we constantly moved around our Home and CategoriesList widgets to see some changes. Let's build a navigation bar to have a better user experience:

Reset Our Home Page

Let's revert our Last lesson change from Categories List to Home:

lib/main.dart

// ...
return MultiProvider(
  child: MaterialApp(title: 'Welcome to Flutter', routes: {
    '/': (context) {
      final authProvider = Provider.of<AuthProvider>(context);
      return authProvider.isAuthenticated ? CategoriesList() : Login();
      return authProvider.isAuthenticated ? Home() : Login();
    },

Add Logout to Our Authentication Provider
