 From My own medium article - Roadmap to Learn Flutter State Management | by Harshana | Feb, 2025 | Medium


Here’s a structured roadmap to help you learn state management in Flutter. Each section builds on the previous one, so it’s recommended to follow the order. right!






1. Understanding State in Flutter

What to Learn:

  • What is state in Flutter?
  • Difference between Ephemeral State (local state) and App State (global state).
  • How Flutter rebuilds the UI when the state changes.

Key Concepts:

  • setState() for local state management.
  • Widget lifecycle methods (initState, dispose, etc.).

Resources:

  • Flutter documentation on Stateful Widget.
  • Tutorials on basic state management using set State.

2. Basic State Management with setState

What to Learn:

  • How to use setState to manage local state within a single widget.
  • Pros and cons of using setState.

Key Concepts:

  • When to use setState.
  • Limitations of setState for larger apps.

Practice:

  • Build a simple counter app using setState.

3. Lifting State Up

What to Learn:

  • How to share state between widgets by lifting state up to a common ancestor.
  • Passing data down the widget tree using constructors.

Key Concepts:

  • Parent-child communication.
  • Avoiding prop drilling (passing data through multiple layers).

Practice:

  • Build a small app where state is shared between multiple widgets.

4. Introduction to State Management Solutions

What to Learn:

  • Why you need state management solutions for larger apps.
  • Overview of popular state management approaches:
  • Provider
  • Riverpod
  • Bloc/Cubit
  • GetX
  • Redux
  • MobX

Key Concepts:

  • Decoupling UI and business logic.
  • Choosing the right state management approach for your app.

Resources:

5. Provider Package

  • What to Learn:
  • Basics of the Provider package.
  • How to use ChangeNotifier, ChangeNotifierProvider, and Consumer.

Key Concepts:

  • Dependency injection using Provider.
  • Scoped state management.

Practice:

  • Build a simple app using Provider for state management.

6. Riverpod

What to Learn:

  • How Riverpod improves upon Provider.
  • Using Provider, FutureProvider, StreamProvider, Notifier, AsyncNotifier, and StreamNotifier.

Key Concepts:

  • Compile-time safety.
  • Better testability and scalability.

Practice:

  • Refactor a Provider-based app to use Riverpod.

7. Bloc/Cubit

8. GetX

9. Advanced State Management

What to Learn:

  • Combining multiple state management approaches.
  • Handling complex app states (e.g., authentication, database integration).

Key Concepts:

  • State persistence (e.g., using shared_preferences or local databases).
  • Optimizing performance with state management.

Practice:

  • Build a medium-sized app with advanced state management.

10. Testing State Management

What to Learn:

  • How to write unit and widget tests for state management.
  • Testing different state management approaches (Provider, Bloc, GetX, etc.).

Key Concepts:

  • Mocking dependencies.
  • Ensuring state changes are reflected correctly in the UI.

Practice:

  • Write tests for your state management logic.

Summary

Suggested Order of Learning:

  1. Start with Understanding State and Basic State Management with setState.
  2. Move to Lifting State Up to understand sharing state between widgets.
  3. Learn Provider and Riverpod for simple and scalable state management.
  4. Explore Bloc/Cubit for more structured and event-driven state management.
  5. Try GetX for a lightweight and feature-rich alternative.
  6. Dive into Advanced State Management for complex apps.
  7. Finally, learn Testing State Management to ensure your app is robust.
