override
addListener(GetStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
inherited

inherited
any(bool test(E element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
asMap() → Map<int, E>
An unmodifiable Map view of this list.
inherited
bindStream(Stream<List<E>> stream) → void
Binds an existing Stream<T> to this Rx
inherited
call([List<E>? v]) → List<E>
Makes a direct update of value adding it to the Stream useful when you make use of Rx for custom Types to refresh your UI.
inherited
cast<R>() → List<R>
Returns a view of this list as a list of R instances.
inherited
clear() → void
Removes all objects from this list; the length of the list becomes zero.
inherited
close() → void
Close the Rx Variable
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
containsId(Object id) → bool
inherited
containsListener(GetStateUpdate listener) → bool
inherited
dispose() → void
inherited
disposeId(Object id) → void
To dispose an id from future updates(), this ids are registered by GetBuilder() or similar, so is a way to unlink the state change with the Widget from the Controller.
inherited
elementAt(int index) → E
Returns the indexth element.
inherited
every(bool test(E element)) → bool
Checks whether every element of this iterable satisfies test.
inherited

Expands each element of this Iterable into zero or more elements.

Overwrites a range of elements with fillValue.

The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, E element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<E> other) → Iterable<E>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(E element)) → void
Invokes action on each element of this iterable in iteration order.
inherited

Creates an Iterable that iterates over a range of elements.
inherited

The first index of element in this list.
inherited
indexWhere(bool test(E element), [int start = 0]) → int
The first index in the list that satisfies the provided test.
inherited
insert(int index, E element) → void
Inserts element at position index in this list.
inherited
insertAll(int index, Iterable<E> iterable) → void

inherited
listenAndPump(void onData(List<E> event), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<List<E>>
Returns a StreamSubscription similar to listen, but with the added benefit that it primes the stream with the current value, rather than waiting for the next value. This should not be called in onInit or anywhere else during the build process.
