firstOrNullWhere(bool test(T element)) → T?: Returns the first element that satisfies the given predicate test.
group<K>(K by(T item)) → Map<K, List<T>>: Groups Iterable via K by(T item)
groupMap<K, V>(K by(T item), V as(List<T> item)) → Map<K, V>: Groups Iterable via K by(T item) and maps it using V as(List<T> item) conversion.
lastOrNullWhere(bool test(T element)) → T?: Returns the last element that satisfies the given predicate test.
mapList<E>(E f(T e)) → List<E>: Maps Iterable and casts it to a List.
mapWhereList<E>(E f(T e), bool test(E element)) → List<E>: Maps Iterable, then filters Iterable and then casts it to a List.
singleOrNullWhere(bool test(T element)) → T?: Returns the single element that satisfies test.
whereList(bool test(T element)) → List<T>: Filters Iterable and casts it to a List.
whereMapList<E>(bool test(T element), E f(T e)) → List<E>: Filters Iterable, then mapps Iterable and then casts it to a List.
