Overview
A lightweight Flutter package that extends ChangeNotifier to allow fine-grained state updates by observing only specific properties of a model, rather than the entire object. It reduces unnecessary rebuilds in UI components by notifying listeners only when targeted properties change. Ideal for optimizing performance in apps with complex models and frequent updates. The package integrates seamlessly with existing ChangeNotifier workflows and supports all major platforms.
Use cases
- Optimizing UI performance in large stateful widgets
- Reducing unnecessary rebuilds when only part of a model changes
- Managing partial state updates in complex data models
- Improving responsiveness in forms with multiple fields
- Enabling granular control over listener notifications
Key features
- Observer-only specific properties
- Minimal boilerplate
- Seamless integration with ChangeNotifier
- Supports all Flutter platforms
- Efficient rebuilds based on property changes
- Lightweight and easy to adopt
Suitable for
- Developers seeking fine-grained state management
- Apps with complex models requiring partial updates
- Performance-sensitive applications
- Teams using ChangeNotifier already
- Projects aiming to reduce widget rebuilds
Considerations
- Requires careful tracking of which properties to observe
- Not suitable for full-model change scenarios
- Limited to property-level notifications
- May increase complexity for simple use cases
