Methods

containsAll(Iterable<Object?> elements) → bool

Available on Iterable<T>, provided by the IterableExtensions extension

Returns true if Iterable contains all elements.
containsAny(Iterable<Object?> elements) → bool

Available on Iterable<T>, provided by the IterableExtensions extension

Returns true if Iterable contains any of elements.
distinct([Object? key(T element)?]) → List<T>

Available on Iterable<T>, provided by the IterableExtensions extension

Deletes duplicate elements in an array.
equalsTo(Iterable<T> others) → bool

Available on Iterable<T>, provided by the IterableExtensions extension

Returns true if the internals of Iterable and others are compared and match.
expandAndRemoveEmpty<TCast>(Iterable<TCast?> callback(T item)) → List<TCast>

Available on Iterable<T>, provided by the IterableExtensions extension

Each element of the list is converted to TCast data using callback.
firstWhereOrNull(bool test(T item)) → T?

Available on Iterable<T>, provided by the IterableExtensions extension

Returns the first element for which the return value of test is true.
insertEvery(T value, int per) → Iterable<T>

Available on Iterable<T>, provided by the IterableExtensions extension

Inserts a value element for each per of Iterable.
lastWhereOrNull(bool test(T item)) → T?

Available on Iterable<T>, provided by the IterableExtensions extension

Returns the last element for which the return value of test is true.
limit(int start, int end) → List<T>

Available on Iterable<T>, provided by the IterableExtensions extension

Extract only the elements from start to end of Iterable.
limitEnd(int end) → List<T>

Available on Iterable<T>, provided by the IterableExtensions extension

Extract only the elements to end of Iterable.
limitStart(int start) → List<T>

Available on Iterable<T>, provided by the IterableExtensions extension

Extract only the elements from start of Iterable.
mapAndRemoveEmpty<TCast>(TCast? callback(T item)) → List<TCast>

Available on Iterable<T>, provided by the IterableExtensions extension

Each element of the list is converted to TCast data using callback.
print() → void

Available on Iterable<T>, provided by the IterableExtensions extension

print the entire contents of List.
setWhere<K extends Object>(Iterable<T> others, {required bool test(T original, T other), required K? apply(T original, T other), K? orElse(T original)?}) → Iterable<K>

Available on Iterable<T>, provided by the IterableExtensions extension

If others is given to Iterable and the return value of test is true, the return value of apply is replaced with the corresponding value of Iterable.
split(int length) → Iterable<Iterable<T>>

Available on Iterable<T>, provided by the IterableExtensions extension

Iterable is divided into length elements each, creating a list of lists.
splitWhere(bool test(T a, T b)) → Iterable<Iterable<T>>

Available on Iterable<T>, provided by the IterableExtensions extension

Groups Iterable together with elements that have a return value of true for test and returns a list of each group.
toMap<K, V>(MapEntry<K, V>? f(T item)) → Map<K, V>

Available on Iterable<T>, provided by the IterableExtensions extension

The callback given by f from Iterable will create a map of K and V.
