🛠 StateNotifier Class

What is it?
Think of StateNotifier like a magic box where we store important information, like a score in a game. When the score changes, it shouts out to everyone that it's been updated!

How it works:

• We create a StateNotifier with a starting score.
• If the score changes, StateNotifier tells everyone who’s listening, like other parts of your app, to update and show the new score!

Fun part 🎉: You can add or remove listeners, like telling certain parts of the app to pay attention when the score changes.

---

🔧 Features

• 🔄 Reactive State Management: Automatically update UI components when the state changes.
• 💪 Simple Widget Binding: Use the Shared class to bind Flet widgets dynamically to shared states.
• 🔧 Formatter Support: Customize how state values are displayed with flexible formatting strings.
• 🌍 Complex Widget Attributes: Update attributes like content, value, or controls dynamically.
• ⏳ Detachable Listeners: Add or remove widgets from state listeners as needed.
• 🚀 Inline State Updates: Use intuitive operations like shared_state.value += 1.
• 📓 Easy to Learn and Use: Minimal learning curve with a clean, developer-friendly

🔗 Shared Class

What is it?
Imagine you have a cool widget (like a score display) and you want it to automatically change when the score updates. Shared makes this happen!

How it works:

• Shared links the score widget to the StateNotifier (the magic box from above).
• When the score changes, the widget instantly updates itself to show the new score. No need to do anything manually!

What’s special 💫:

• If you have a special formatting (like showing the score as “Score: 10”), you can tell Shared to format it for you.
• It will always keep the widget in sync with the score!

---

🧑‍🏫 How They Work Together:

• StateNotifier keeps the score (or any value) safe.
• Shared makes sure your widgets (like score displays) stay updated with the new value whenever it changes!

It’s like a team where one member holds the information (StateNotifier) and the other makes sure everything looks correct and up-to-date (Shared).

And that’s how you make your app super interactive! 🎮

Routing Modes 🚥

Basic Routing 🚶‍♂️

Basic routing allows you to manage navigation between pages in a simple way, using predefined methods like swap, reach, back, and refresh.

How it works:

here function means : the function which return ui like return [ft.Container(height=100) ]

1. swap(route, function): This method adds a new page to the views stack and navigates to it. It appends the new view without removing the existing ones.
2. reach(route, function): This method replaces the entire view stack with a new page.
3. back(): This method allows you to go back to the previous view.
4. refresh(): This method refreshes the current view.

To activate Basic Routing, you just need to call the app with advanced_routing=False:

enhanced_app(target, advanced_routing=False)

Example:

def home_page(page):
    return Column([Text("Welcome to Home!")])

def about_page(page):
    return Column([Text("About Us")])

# Basic Routing with swap and reach methods
page.swap("/home", home_page)
page.reach("/about", about_page)

---

Advanced Routing 🚀

Advanced routing gives you more control by using RoutingConfig to register routes, middlewares, and error pages. This mode is ideal for complex applications where you need more flexibility.

How it works:

1. RoutingConfig.register_route: Register routes with optional guards, custom redirects, and custom error pages.
2. apply_middlewares: Apply middleware functions to routes for conditions like authentication.
3. Global error pages: Define custom error pages for "404", "not allowed", etc.

To activate Advanced Routing, you call the app with advanced_routing=True:

enhanced_app(target, advanced_routing=True)

Example:

page.register_route("/home", home_page)
page.register_route("/about", about_page)
page.set_global_error_page("404", page_not_found)
page.register_middleware(auth_middleware)

---

Switch Between Routing Modes 🔄

You can easily switch between Basic and Advanced routing modes:

• For Basic Routing, set advanced_routing=False:

  enhanced_app(target, advanced_routing=False)
  

• For Advanced Routing, set advanced_routing=True:

  enhanced_app(target, advanced_routing=True)
  

When to Choose Which? 🤔

🚗 Basic Routing: Best for mobile and desktop apps, providing simple and fast navigation.
🏎️ Advanced Routing: Perfect for websites and web apps, supporting complex setups with middleware and role-based access.
