collections library

Adding methods for collection control.

Classes

Grouping<T, K>

Serves as an step between grouping and folding operations.

Pair<T, V>

Extensions

Associate on Iterable<T>

Chunked on Iterable<T>

FilterNotNull on Iterable<T?>

FirstOrNull on Iterable<T>

GetOrNull on Iterable<T>

GetOrPut on Map<K, V>

GroupingBy on Iterable<T>

MapIndexed on Iterable<T>

MapNotNull on Iterable<T>

RangeNum on T

SingleOrNull on Iterable<T>

ZipWithNext on List<T>

Functions

range<T extends num>(T value, {T? to, T? until, T? downTo, T? step}) → List<T>

Creates progression ranges of given type value.

repeat<T>(int iterations, T lambda(int index)) → List<T>

The repeat method allows you to easily call a lambda a certain number of times.

Typedefs

AggregateOperation<T, K, R> = R Function(K key, R? accumulator, T element, bool first)

A function that is invoked on each element.

ChunkedTransform<T, R> = R Function(T chunk)
