If you are building a custom surface API, start with docs/guide.md for the step-by-step preset and system workflows.

Avoiding Leaky Effects

Always retain and stop effects you create in long-lived contexts.

final stop = effect(() => print(count()));
// later
stop();

Use scopes when multiple effects should stop together.

final scope = effectScope(() {
  effect(() => print('one ${count()}'));
  effect(() => print('two ${count()}'));
});
// later
scope();

Batch writes to avoid redundant effect runs.

startBatch();
count.set(1);
count.set(2);
endBatch();

Prefer computed for derived values; it caches and reuses results.

final total = computed((prev) => price() * qty());

Use trigger to notify dependents without creating a long-lived effect.

trigger(() {
  count();
});
