🌟 What is Alien Signals? #

Alien Signals is a reactive state management library that brings the power of signals to Dart and Flutter applications. Originally inspired by StackBlitz's alien-signals, our Dart implementation provides:

• 🪶 Ultra Lightweight: Minimal overhead, maximum efficiency
• 🎯 Simple API: Intuitive signal(), computed(), and effect() functions
• 🔧 Production Ready: Battle-tested through comprehensive beta releases

🚀 Key Features #

Core Reactive Primitives #

import 'package:alien_signals/alien_signals.dart';

void main() {
  // Create reactive state
  final count = signal(0);

  // Create derived state
  final doubled = computed((_) => count() * 2);

  // Create side effects
  effect(() {
    print('Count: ${count()}, Doubled: ${doubled()}');
  });

  // Update state - triggers all dependencies
  count.set(1); // Output: Count: 1, Doubled: 2
}

Advanced Features #

• Effect Scopes: Group and manage effects together
• Batch Operations: Control when reactivity updates occur
• Flexible API: Both high-level presets and low-level system access

📦 Installation #
