Utility mixins and tools for Levit Flutter applications. Re-exports levit_dart_utility.

levit_flutter

Official Flutter integration for the Levit ecosystem.

levit_flutter provides the necessary glue to connect Levit's high-performance reactive state (levit_reactive) and hierarchical dependency injection (levit_scope) with the Flutter widget tree.

---

Purpose & Scope

levit_flutter is the primary entry point for Flutter developers. It is responsible for:

• Binding reactive state updates to widget rebuilds with minimal overhead.
• Providing widgets for scope management and dependency propagation.
• Offering lifecycle-aware hooks and widgets for clean resource management in the UI.

---

Conceptual Overview

Core Abstractions

• [LWatch]: A widget that automatically rebuilds when reactive variables it accesses change.
• [LView]: A controlled view that lifecycle-manages its own scoped dependencies.
• [LScope]: A widget that injects a [LevitScope] into the subtree.

Getting Started

Watching State

final count = 0.lx;

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return LWatch(() => Text('Count: ${count.value}'));
  }
}

---

Design Principles

Precision Rebuilds

Granular reactivity ensures that only the specific widgets reading a piece of state are rebuilt, avoiding full subtree re-renders.

Intuitive Scoping

Leverages Flutter's InheritedWidget patterns to make dependency injection feel natural and integrated with the framework's architecture.
