poc_bloc

BLoC (short for Business Logic Component) is a design pattern in Flutter used to separate business logic from UI. It helps manage and organize state and event handling in a clean and scalable way, especially in large applications.

🔧 Key Concepts of BLoC:

1. Event: An action triggered by the user (e.g., button press, text input).

2. State: The UI state that should be shown in response to events.

3. BLoC: A component that:

   • Takes in Events
   • Processes logic
   • Emits new States to update the UI

---

📦 Common BLoC Tools:

• flutter_bloc: A package that provides easy-to-use BLoC architecture.
• BlocBuilder: Widget that rebuilds UI based on new states.
• BlocProvider: Makes a BLoC available to the widget tree.

---

🧠 Example Use Case:

Imagine a counter app:

1. Event: IncrementCounter
2. State: CounterState(count: x)
3. BLoC: Handles the event, updates the count, emits a new state
4. UI: Uses BlocBuilder to listen to state changes and rebuild

✅ Why Use BLoC?

• Promotes clean architecture
• Encourages testable and reusable code
• Ideal for scaling apps with complex logic and multiple screens
• Reactive: BLoC works well with Streams, making state management dynamic

---

🚫 Downsides:

• Can feel boilerplate-heavy
• Might be overkill for small apps or simple widgets
