BloomKeyedIterableElementsExtension<E> extension

Extension on Bloom<Iterable<E>> providing keyed element-wise transformations via .keyed.

Keyed operations preserve downstream value/node cache across source collection updates, eliminating expensive re-evaluations by caching results based on stable unique keys.

Examples

final users = blooming([User(id: '1', name: 'Alice')]);
final userViewModels = users.bloom.keyed.map(
  key: (user) => user.id,
  convert: (user) => UserViewModel(user),
  update: (vm, user) => vm.update(user),
);
