final count = signal(0);
final clicks = signal(0);

void incrementCount() {
  count.value++;
  clicks.value++;
}

// Create a batched, untracked action from the function
final increment = incrementCount.action;

void main() {
  effect(() => print('Count: ${count.value}, Clicks: ${clicks.value}'));
  // Prints: "Count: 0, Clicks: 0"

  increment();
  // Updates both count and clicks inside a batch.
