Methods

add(T item, {bool notify = true}) → void
Adds item to the end of this list, extending the length by one.
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.
inherited
asNameMap() → Map<String, T>

Available on Iterable<T>, provided by the EnumByName extension

Creates a map from the names of enum values to the values.
byName(String name) → T

Available on Iterable<T>, provided by the EnumByName extension

Finds the enum value in this list with name name.
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
clear({bool notify = true}) → 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.
inherited
deserialize(dynamic map) → void
Deserializes a map of items with the help of deserializeItem.
inherited
deserializeItem(dynamic data) → T
Returns a new T from the provided serialized data.
inherited
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 will throw after the object is disposed).
inherited
elementAt(int index) → T
Returns the indexth element.
inherited
elementAtOrNull(int index) → T?

Available on Iterable<T>, provided by the IterableExtensions extension

The element at position index of this iterable, or null.
every(bool test(T element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(T element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(T element), {T orElse()?}) → T
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, T element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<T> other) → Iterable<T>
Creates the lazy concatenation of this iterable and other.
inherited
forceNotify() → void
If for some reason one needs to call notifier, they can call forceNotify
forEach(void action(T element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
fromId(String id) → T
Return the element with specified id.
inherited
indexWhere(bool test(T element), [int start = 0]) → int
The first index in the list that satisfies the provided test.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(T element), {T orElse()?}) → T
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(T e)) → Iterable<T>
This is a simple interface to the map method of the list
inherited
move(int oldIndex, int newIndex, {bool notify = true}) → void
Moves an item from one position to another
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
remove(dynamic value, {bool notify = true}) → void
Removes a single item from the list.
override
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
replace(T item, {bool notify = true}) → void
Updates the value of item.
override
serialize() → Map<String, dynamic>
Serializes all of its items into a single map, separted by their id.
inherited
singleWhere(bool test(T element), {T orElse()?}) → T
The single element that satisfies test.
inherited
skip(int count) → Iterable<T>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(T value)) → Iterable<T>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<T>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(T value)) → Iterable<T>
Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<T>
Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<T>
Creates a Set containing the same elements as this iterable.
inherited
toString() → String
Returns a string representation of (some of) the elements of this.
inherited
