expand<T>(Iterable<T> toElements(E element)) → Iterable<T>

Available on Obj<Iterable<E>>, provided by the ObjIterableExt extension

Expands each element of this Iterable into zero or more elements.

firstWhere(bool test(E element), {E orElse()?}) → E

Available on Obj<Iterable<E>>, provided by the ObjIterableExt extension

Returns the first element that satisfies the given predicate test.

fold<T>(T initialValue, T combine(T previousValue, E element)) → T

Available on Obj<Iterable<E>>, provided by the ObjIterableExt extension

Reduces a collection to a single value by iteratively combining each element of the collection with an existing value

followedBy(Iterable<E> other) → Iterable<E>

Available on Obj<Iterable<E>>, provided by the ObjIterableExt extension
