Methods

all(bool test(T element)) → bool
Checks whether ALL element of this iterable satisfies test. Returns false if isEmpty.
combinations<E>(int minimumSize, int maximumSize, {bool allowRepetition = true, bool checkAlphabet = true, Iterable<E> mapper(T e)?, bool validator(List<E> combination)?}) → List<List<E>>
Generate combinations using this Iterable elements as an alphabet.
comparator({Comparator<T>? compare, T? sample}) → Comparator<T>
Tries to returns a Comparator<T> for this instance. Validates compare if provided.
computeHashcode() → int
Computes the hashcode of this Iterable, using IterableEquality defaults.
containsAll(Iterable<T> other) → bool
Returns true if this contains all elements of other.
containsAny(Iterable<T> other) → bool
Returns true if this contains at least 1 elements of other.
copy() → Iterable<T>
Copies this Iterable preserving the original type if possible or returns a copy as List.
equalsElements(Iterable<T> other) → bool
Returns true if all the elements are equals to other elements.
groupBy<G>(G grouper(T e)) → Map<G, List<T>>
Groups elements by grouper.
printElements({dynamic printer(Object? o)?, String? prefix}) → void
Print the elements.
toMap<K, V>(K keyMapper(T e), V valueMapper(T e)) → Map<K, V>
Converts this List to a Map.
toStringsList() → List<String>
Returns a List
whereIn(Iterable other, {Object? view(T e)?}) → Iterable<T>
Returns a new lazy Iterable with all elements contained in other.
whereNotIn(Iterable other, {Object? view(T e)?}) → Iterable<T>
Returns a new lazy Iterable with all elements NOT contained in other.
