Methods

add(E valueToAdd) → void
Adds value to the end of this list, extending the length by one.
addAll(Iterable<E> iterable) → void
Appends all objects of iterable to the end of this list.
asMap() Map<int, E>?
An unmodifiable Map view of this list.
cast<R>() List<R>?
Returns a view of this list as a list of R instances.
clear() → void
Removes all objects from this list; the length of the list becomes zero.
fillRange(int start, int end, [E? fillValue]) → void
Overwrites a range of elements with fillValue.
getRange(int start, int end) Iterable<E>?
Creates an Iterable that iterates over a range of elements.
indexOf(E element, [int start = 0]) int?
The first index of element in this list.
indexWhere(bool test(E element), [int start = 0]) int?
The first index in the list that satisfies the provided test.
insert(int index, E element) → void
Inserts element at position index in this list.
insertAll(int index, Iterable<E> iterable) → void
Inserts all objects of iterable at position index in this list.
lastIndexOf(E element, [int? start]) int?
The last index of element in this list.
lastIndexWhere(bool test(E element), [int? start]) int?
The last index in the list that satisfies the provided test.
remove(Object? valueToRemove) bool?
Removes the first occurrence of value from this list.
removeAt(int index) → E?
Removes the object at position index from this list.
removeLast() → E?
Removes and returns the last object in this list.
removeRange(int start, int end) → void
Removes a range of elements from the list.
removeWhere(bool test(E element)) → void
Removes all objects from this list that satisfy test.
replaceRange(int start, int end, Iterable<E> replacements) → void
Replaces a range of elements with the elements of replacements.
retainWhere(bool test(E element)) → void
Removes all objects from this list that fail to satisfy test.
setAll(int index, Iterable<E> iterable) → void
Overwrites elements with the objects of iterable.
setRange(int start, int end, Iterable<E> iterable, [int skipCount = 0]) → void
Writes some elements of iterable into a range of this list.
shuffle([Random? random]) → void
Shuffles the elements of this list randomly.
sort([int compare(E a, E b)?]) → void
Sorts this list according to the order specified by the compare function.
sublist(int start, [int? end]) List<E>?
Returns a new list containing the elements between start and end.

Operators

operator [](int index) → E?
The object at the given index in the list.
operator []=(int index, E valueToSet) → void
Sets the value at the given index in the list to value.
