A reactive effect that runs side effects in response to signal changes.
Effects automatically track their dependencies and re-run when any dependency changes. They are useful for performing side effects like DOM updates, logging, or API calls.
Use the call method to stop the effect and clean up its subscriptions.
Example:
final count = signal(0);
final dispose = effect(() {
print('Count is: ${count()}');
});
// Later, stop the effect:
dispose();
