Flutter developers are spoiled for choice when it comes to state management. From BLoC to Riverpod, the ecosystem is rich. However, as our apps grow in complexity, we often find ourselves fighting a common enemy: unnecessary UI rebuilds.
Today, I’m excited to introduce the latest updates to Flutter Rocket—a lightweight, high-performance state management and API integration solution that puts "Premium Performance" at the center of your development workflow.
The Performance Bottleneck: The "Rebuild Everything" Syndrome
We’ve all been there. You update a user’s biography in a deep nested object, and suddenly your entire profile screen—including the avatar, interest tags, and post history—rebuilds. In large lists, updating one item can sometimes trigger an expensiv…
Flutter developers are spoiled for choice when it comes to state management. From BLoC to Riverpod, the ecosystem is rich. However, as our apps grow in complexity, we often find ourselves fighting a common enemy: unnecessary UI rebuilds.
Today, I’m excited to introduce the latest updates to Flutter Rocket—a lightweight, high-performance state management and API integration solution that puts "Premium Performance" at the center of your development workflow.
The Performance Bottleneck: The "Rebuild Everything" Syndrome
We’ve all been there. You update a user’s biography in a deep nested object, and suddenly your entire profile screen—including the avatar, interest tags, and post history—rebuilds. In large lists, updating one item can sometimes trigger an expensive redraw of the whole view.
Flutter Rocket 1.1.0 changes that.
1. Selective Rebuilds: Precision UI Updates
The star of the show is Selective Rebuilds. This feature allows you to specify exactly which properties a widget should listen to.
Instead of rebuilding every time a model changes, your widget only reacts when the specific "fields" it depends on are updated.
// This widget ONLY rebuilds when 'title' changes
RocketView(
model: currentPost,
fields: [postTitleField],
builder: (context, state) => Text(currentPost.title!),
)
By localizing updates to the property level, you drastically reduce CPU cycles, save battery, and ensure a silky-smooth 60 (or 120!) FPS experience even on lower-end devices.
2. Automatic Bubbling: Zero-Code Orchestration
Managing state in nested collections is usually a headache. If a Post changes, how does the Posts list know it needs to refresh its summary?
With Automatic Bubbling, Flutter Rocket handles this orchestration for you. When a child model triggers an update, it automatically "bubbles up" to its parent collection.
The result? Your UI stays perfectly in sync across different screens and components without you writing a single line of manual listener code.
3. Rocket CLI: The Magic Wand 🪄
Performance optimizations are great, but no one likes writing boilerplate. That’s why we’ve updated Rocket CLI to version 1.1.0.
Now, when you generate your models from JSON, the CLI automatically generates the updateFields logic required for Selective Rebuilds and Bubbling.
# Generate a fully optimized model in seconds
rocket_cli -j '{"id":1, "title":"Hello World"}' -n Post
You get industry-leading performance out of the box, generated in a single command.
Why Flutter Rocket?
Flutter Rocket isn’t just another state management library. It’s a complete ecosystem:
- RocketModel: Smart data structures with built-in state.
- RocketClient: HTTP client with interceptors and dynamic caching.
- RocketView: Smart widgets that handle loading, errors, and data binding.
- Rocket Singleton: A global registry to access your data from anywhere.
