Quick Start

Here's a simple example demonstrating how to use Oref:

import 'package:oref/oref.dart';

void main() {
  final count = ref(0);
  final doubleCount = derived(() => count.value * 2);

  effect(() {
    print('Count: ${count.value}, Double: ${doubleCount.value}');
  });

  count.value++; // Will trigger the effect and print new values
}
