Safe dependency tracking in Dart signals requires dynamic subscription management during reads, ensuring effects and computed values only subscribe to dependencies actually accessed. Lazy evaluation and memoization prevent unnecessary recomputations.

Batching in Dart preact signals groups multiple signal updates into a single transactional propagation, preventing intermediate recomputations. It ensures synchronous reactivity contexts only trigger effects after the batch completes.

Preventing memory leaks and cycles in Dart reactive primitives requires strict re-entrancy safety guards, proper cleanup of effect subscriptions, and dynamic dependency updates that remove stale references during signal propagation.

Untracked reads in Dart signals allow you to access current signal values without creating dependency subscriptions. This is essential for reading state inside effects or computed values without triggering reactivity loops.

Lazy evaluation in Dart computed signals defers calculation until the value is read, while memoization caches the result until dependencies change. This ensures purity expectations and avoids redundant recomputations in synchronous contexts.
