ð 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:
- ðŠķ Ultra Lightweight: Minimal overhead, maximum efficiency
- ðŊ Simple API: Intuitive
signal(),computed(), andeffect()functions - ð§ Production Ready: Battle-tested through comprehensive beta releases
ð 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
ðĶ Installation
