TransformBridgeSignal<N extends NodeInterface, S, V> class

A bridge that transforms a parent signal's value into a different type.

N is the parent node type. S is the source signal type. V is the transformed value type (can differ from S, value is nullable).

late final order = registerSignal(
  TransformBridgeSignal(
    select: (OrdersNode node) => node.orders,
    transform: (orders) => orders.firstWhereOrNull((o) => o.id == id),
    update: (node, value) {
      if (value == null) return;
      node.updateOrder(value);
    },
  ),
);
