-
fillRange(int start, int end, [E? fillValue])
→ void
-
Overwrites a range of elements with
fillValue.
-
getRange(int start, int end)
→ Iterable<E>?
-

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?
-

-
removeAt(int index)
→ E?
-
Removes the object at position
index from this list.
-
removeLast()
→ E?
-

-
removeRange(int start, int end)
→ void
-

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

start and end.
Operators
-
operator [](int index)
