• Solidart - ❤️ Signals in Dart and Flutter, inspired by SolidJS
• Oref - 🪄 A Flutter package that brings hooks-like magic to widgets using signals

import 'package:alien_signals/alien_signals.dart';
void main() {
  // Create a signal
  final count = signal(0);
  // Create a computed value
  final doubled = computed((_) => count() * 2);
  // Create an effect
  effect(() {
    print('Count: ${count()}, Doubled: ${doubled()}');
  });
  // Update the signal
  count(1); // Prints: Count: 1, Doubled: 2
}
