Overview
Event Bus is a lightweight Dart package that uses Streams to enable event-driven communication between components in an application. It promotes loose coupling by allowing objects to publish events and subscribe to them without direct dependencies. Ideal for coordinating actions across different parts of an app, such as UI updates, state changes, or cross-module interactions. The package is simple to integrate and works seamlessly across all major platforms supported by Flutter.
Use cases
- Decoupling UI components
- Handling global state changes
- Broadcasting app-wide notifications
- Simplifying inter-module communication
- Managing asynchronous events
- Reducing boilerplate in state management
Key features
- Stream-based event delivery
- Simple publish/subscribe pattern
- Cross-platform compatibility
- Minimal API surface
- Supports typed events
- No external dependencies
Suitable for
- Apps needing loose coupling
- Developers avoiding complex state managers
- Projects with frequent inter-component communication
- Prototyping rapid event flows
- Teams preferring simplicity over configuration
Considerations
- Not suitable for large-scale state management
- Limited built-in error handling
- Requires careful event naming to avoid collisions
- Does not persist events across app restarts
- Best used alongside other state management solutions for complex apps
