no setter

Methods

allEquals(T element) → bool
Returns true if all elements are equals to element.
asDoubles() → List<double>
Returns this instance as a List
asInts() → List<int>
Returns this instance as a List
binarySearchPoint(T key, {int start = 0, int? end, Comparator<T>? compare}) → int
A binary search that returns:
computeHashcode() → int
Computes the hashcode of this List, using ListEquality defaults.
ensureMaximumSize(int maximumSize, {bool removeFromEnd = false, int removeExtras = 0}) → int
Ensures that this List.length is not bigger than maximumSize.
equalsElements(List<T> other) → bool
Returns true if all the elements are equals to other elements.
getReversed(int reversedIndex) → T
Returns the elements at reversedIndex (index: [lastIndex - reversedIndex]).
getValueIfExists(int index) → T?
Returns the element at index. Returns null if out of range.
Head of this List with size.
headByRatio(double sizeRatio, {int? minimumSize}) → List<T>
Head of this List with size based the in sizeRatio of length. See lengthRatio.
lengthRatio(double ratio, {int? minimumSize}) → int
Returns the length multiplied by ratio.
randomSelection({int? length, double? lengthRatio, int? minimumSize, Random? random, int? seed}) → List<T>
removeAll(Iterable other) → void
Remove from this List all the elements contained in other.
removeFromBegin(int amount) → int
Remove an amount of elements from the beginning.
removeFromEnd(int amount) → int
Remove an amount of elements from the end.
resampleByIndex<R>(RangeSelectorFunction<T, RangeSelectionByIndex<T>> selector, List<R> merger(List<T> sel), {bool skipResampledIndexes = true}) → List<R>
Resample elements by index range (RangeSelectionByIndex).
resampleByValue<R>(RangeSelectorFunction<T, RangeSelectionByValue<T>> selector, List<R> merger(List<T> sel), {bool skipResampledIndexes = true, Comparator<T>? compare}) → List<R>
Resample elements by value range (RangeSelectionByValue).
retainAll(Iterable other) → void
Retain in this List all the elements contained in other.
searchInsertSortedIndex<E, K>(T key, {int start = 0, int? end, Comparator<T>? compare}) → int
Returns the index to insert key and keep the List sorted.
setAllWith(T f(int index, T value)) → int
Set all elements of this instance with values from f.
setAllWithList(List<T> list, [int offset = 0]) → int
Set all elements of this instance with list, starting from list offset.
setAllWithValue(T value) → int
Set all elements of this instance with value.
shuffleCopy({Random? random, int? seed}) → List<T>
sublistReversed(int endReversed, [int? startReversed]) → List<T>
Sames as sublist, but with reversed parameters indexes endReversed and startReversed.
tail(int size) → List<T>
Tail of this List with size.
tailByRatio(double sizeRatio, {int? minimumSize}) → List<T>
Tail of this List with size based the in sizeRatio of length. See lengthRatio.
toDistinctList() → List<T>
Converts to a list of distinct elements. Same as toSet().toList() but in a optimized way for small sets.
toStringElements() → List<String>
Creates a new List<String>, mapping each element to a String.
