Methods

add(T value) → void
Adds value to the end of this list, extending the length by one.
override
addAll(Iterable<T> iterable) → void
Appends all objects of iterable to the end of this list.
override
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
any(bool test(T element)) bool
Checks whether any element of this iterable satisfies test.
override
asMap() Map<int, T>
An unmodifiable Map view of this list.
override
cast<E>() List<E>
Returns a view of this list as a list of R instances.
override
clear() → void
Removes all objects from this list; the length of the list becomes zero.
override
contains(Object? element) bool
Whether the collection contains an element equal to element.
override
dependOn(Listenable listenable, [List<T> filter(List<T> origin)?]) → void
Sends a notification to itself when the target listenable is updated.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener and removeListener will throw after the object is disposed).
override
elementAt(int index) → T
Returns the indexth element.
override
every(bool test(T element)) bool
Checks whether every element of this iterable satisfies test.
override
expand<E>(Iterable<E> f(T element)) Iterable<E>
Expands each element of this Iterable into zero or more elements.
override
fillRange(int start, int end, [T? fillValue]) → void
Overwrites a range of elements with fillValue.
override
firstWhere(bool test(T element), {T orElse()?}) → T
Returns the first element that satisfies the given predicate test.
override
fold<E>(E initialValue, E combine(E previousValue, T element)) → E
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
override
followedBy(Iterable<T> other) Iterable<T>
Returns the lazy concatenation of this iterable and other.
override
forEach(void f(T element)) → void
Applies the function f to each element of this collection in iteration order.
override
getRange(int start, int end) Iterable<T>
Creates an Iterable that iterates over a range of elements.
override
indexOf(T element, [int start = 0]) int
The first index of element in this list.
override
indexWhere(bool test(T element), [int start = 0]) int
The first index in the list that satisfies the provided test.
override
insert(int index, T element) → void
Inserts element at position index in this list.
override
insertAll(int index, Iterable<T> iterable) → void

override
join([String separator = ""]) String
Converts each element to a String and concatenates the strings.
override
lastIndexOf(T element, [int? start]) int
The last index of element in this list.
override
lastIndexWhere(bool test(T element), [int? start]) int
The last index in the list that satisfies the provided test.
override
lastWhere(bool test(T element), {T orElse()?}) → T
Returns the last element that satisfies the given predicate test.
override
map<E>(E f(T e)) Iterable<E>
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
reduce(T combine(T value, T element)) → T
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.

inherited
removeRange(int start, int end) → void
