Methods

binarySearch(E element, int compare(E, E)) → int

Available on List<E>, provided by the ListExtensions extension

Returns the index of element in this sorted list.
binarySearchBy<K extends Comparable<K>>(E element, K keyOf(E element), [int start = 0, int? end]) → int

Available on List<E>, provided by the ListExtensions extension

Returns the index of element in this sorted list.
binarySearchByCompare<K>(E element, K keyOf(E element), int compare(K, K), [int start = 0, int? end]) → int

Available on List<E>, provided by the ListExtensions extension

Returns the index of element in this sorted list.
elementAtOrNull(int index) → E?

Available on List<E>, provided by the ListExtensions extension

The indexth element, or null if there is no such element.
equals(List<E> other, [Equality<E> equality = const DefaultEquality()]) → bool

Available on List<E>, provided by the ListExtensions extension

Whether other has the same elements as this list.
expandIndexed<R>(Iterable<R> expand(int index, E element)) → Iterable<R>

Available on List<E>, provided by the ListExtensions extension

Expands each element and index to a number of elements in a new iterable.
forEachIndexed(void action(int index, E element)) → void

Available on List<E>, provided by the ListExtensions extension

Takes an action for each element.
forEachIndexedWhile(bool action(int index, E element)) → void

Available on List<E>, provided by the ListExtensions extension

Takes an action for each element and index as long as desired.
forEachWhile(bool action(E element)) → void

Available on List<E>, provided by the ListExtensions extension

Takes an action for each element as long as desired.
lowerBound(E element, int compare(E, E)) → int

Available on List<E>, provided by the ListExtensions extension

Returns the index where element should be in this sorted list.
lowerBoundBy<K extends Comparable<K>>(E element, K keyOf(E), [int start = 0, int? end]) → int

Available on List<E>, provided by the ListExtensions extension

Returns the index where element should be in this sorted list.

Available on List<E>, provided by the ListExtensions extension

Returns the index where element should be in this sorted list.
mapIndexed<R>(R convert(int index, E element)) → Iterable<R>

Available on List<E>, provided by the ListExtensions extension

Available on List<E>, provided by the ListExtensions extension

A fixed length view of a range of this list.
slices(int length) → Iterable<List<E>>

Available on List<E>, provided by the ListExtensions extension

Contiguous slices of this with the given length.
sortBy<K extends Comparable<K>>(K keyOf(E element), [int start = 0, int? end]) → void

Available on List<E>, provided by the ListExtensions extension

Sorts elements by the natural order of their keyOf property.
sortByCompare<K>(K keyOf(E element), int compare(K a, K b), [int start = 0, int? end]) → void

Available on List<E>, provided by the ListExtensions extension

Sorts elements by the compare of their keyOf property.
