MultiReactiveBuilder class

A widget that observes changes in multiple reactive variables and triggers a rebuild when any variable changes.

MultiReactiveBuilder listens to a list of reactive variables and rebuilds whenever any of them changes. This is useful when your UI depends on multiple reactive state values.

Example:

final name = Reactive<String>('John');
final age = Reactive<int>(25);
final city = Reactive<String>('NYC');

MultiReactiveBuilder(
  reactives: [name, age, city],
  builder: (context) {
    return Text('${name.value}, ${age.value}, ${city.value}');
  },
  listener: () {
    debugPrint('One of the values changed');
  },
  buildWhen: () => age.value >= 18,  // Only rebuild when age >= 18
  listenWhen: () => name.value.isNotEmpty,  // Only listen when name is not empty
);
