What Exactly is State Management in Flutter?

State management refers to managing data across widgets, screens, and over time in a Flutter application. As an app grows, it becomes harder to pass data between screens and widgets manually.

Without state management, UI code ends up directly accessing and mutating data sources. This scenario leads to messy, difficult-to-understand code. 

State management solutions abstract states away from UI code and enable a single source of truth for data. This scenario further simplifies building complex UIs that require data from multiple sources.

Popular state management packages provide concepts like:

• Streams/Observables – Update UIs based on state changes
• Repositories/Stores – Central data stores
• Business logic components – Encapsulate state update logic
• Dependency injection – Provide data stores to components

With state management, Flutter apps have:

More readable and maintainable code

Increased testability

Simpler state sharing across screens

Some popular state management packages provide concepts like:

• Streams/Observables – Update UIs based on state changes (reactive state management)
• Repositories/Stores – Central data stores (centralized state management)
• Business logic components – Encapsulate state update logic (BLoC pattern)
• Dependency injection – Provide data stores to components

These show some state management types available in Flutter, spanning centralized stores to reactive programming.

So, let us explore What is the best state management for Flutter?

Best Flutter State Management Packages

Here are Flutter’s most popular and robust state management options in 2024. This blog post helps answer the question – which package is best for state management in Flutter? Also, explore useful Flutter app development functionalities.

1. Riverpod

Riverpod is a relatively new yet powerful state management library. It builds upon the proven provider package. Riverpod offers a reactive paradigm and catches development faults at compile time instead of runtime.

The Core Ideas in Riverpod include:

• Consumers – Read providers and rebuild on changes
• Notifiers – Update providers

Riverpod uses Streams under the hood to update consumers when providers change.

How does it Precisely Work?

These are the critical steps in Riverpod state management:

1. Declare provider repository for data
2. Wrap app in provider container
3. Components access providers using consumers
4. Interact with providers using notifiers
5. Consumers rebuild UI on provider changes

This architecture separates data sources from presentation code. It enables testable, reactive UIs based on declarative data models.

Key Benefits of Using Riverpod Package

• Simpler than comparable solutions
• Highly testable
• Meant for Flutter specifically

3. BLoC (Business Logic Component) Pattern

The BLoC pattern manages the state in its own component keeping UI separated. It uses Reactive Programming with Streams/Sinks and provides reactive UI updating.

BLoC principles include:

• Business logic as its own component
• One-way data flow
• Easily testable

BLoC is a popular pattern for small to medium-complexity apps. It provides orderly, testable state management.

How does it Precisely Work?

BLoC state management follows:

1. UI component dispatches action to BLoC
2. BLoC handles action
3. BLoC updates Stream with new state
4. StreamBuilder listens for state changes
5. Automatically rebuild UI on state change

Keeping UI separated from business logic improves testability and modularity. BLoC excels at single-purpose tasks.

Key Benefits of Using BLoC Package

• Clear separation of UI and logic
• Familiar Reactive paradigm
• Lightweight, simple management

Provider features:

• Lightweight, built specially for Flutter
• Makes dependencies available anywhere in widget tree
• Multiple provider types for different scenarios
• Encourages separation of business and UI logic
• Prominent ecosystem of addons and guides

Overall, Provider is a great solution for apps new to state management looking for a simple, customizable solution.

How does it Precisely Work?

Basic Provider state management flow:

1. Create a provider repository for the state
2. Make repository available with provider widget
3. Sub widgets access Provider.Of to consume it
4. The repository notifies listeners of change
5. Listenable providers rebuild UI automatically

Separate state update logic is still needed to leverage the Provider fully. But its simple API makes getting started with state management approachable.
