Methods

chunked(int size) → List<List<T>>: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Splits values into fixed-size chunks.
countWhere(bool test(T element)) → int: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Counts elements matching test.
distinctBy<K>(K keyOf(T element)) → List<T>: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Returns a list with duplicates removed by keyOf, preserving order.
none(bool test(T element)) → bool: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Returns true when no element satisfies test.
singleWhereOrNull(bool test(T element)) → T?: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Returns the single matching element, or null if zero or multiple match.
sortedBy<K extends Comparable<Object?>>(K keyOf(T element), {bool descending = false}) → List<T>: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Returns a sorted copy by comparable keyOf.
windowed(int size, {int step = 1, bool partialWindows = false}) → List<List<T>>: Available on Iterable<T>, provided by the IterableQueryExtensions extension
Returns sliding windows of size.
