Rx<T> class

Foundation class used for custom Types outside the common native Dart types. For example, any custom "Model" class, like User().obs will use Rx as wrapper.

Properties

firstRebuild ↔ bool
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
isDisposed → bool
no setterinherited
listenersLength → int
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sentToStream ↔ bool
getter/setter pairinherited
stream → Stream<T>
The stream of values.
no setterinherited
string → String
Same as toString() but using a getter.
no setterinherited
subject → StreamController<T>
The subject stream controller for broadcasting updates.
no setterinherited
value ↔ T
The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.

Methods

addError(Object error, [StackTrace? stackTrace]) → void
inherited
addListener(GetStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, GetStateUpdate listener) → Disposer
inherited
bindStream(Stream<T> stream) → void
Binds an existing Stream<T> to this Rx
inherited
call([T? v]) → T
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
close() → void
Close the Rx Variable
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
listen(void onData(T)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T>
Calls callback with current value, when the value changes.
inherited
listenAndPump(void onData(T event), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T>
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.
inherited
map<R>(R mapper(T? data)) → Stream<R>
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyGroupChildrens(Object id) → void
inherited
refresh() → void
inherited
refreshGroup(Object id) → void
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void
inherited
reportAdd(VoidCallback disposer) → void
inherited
reportRead() → void
inherited
toJson() → dynamic
Returns the json representation of value.
override
toString() → String
A string representation of this object.
inherited
trigger(T v) → void
Following certain practices on Rx data, we might want to react to certain listeners when a value has been provided, even if the value is the same. At the moment, we ignore part of the process if we .call(value) with the same value since it holds the value and there's no real need triggering the entire process for the same value inside, but there are other situations where we might be interested in triggering this.
inherited
update(T fn(T? val)) → void
Uses a callback to update value internally, similar to refresh, but provides the current value as the argument. Makes sense for custom Rx types (like Models).

Operators

operator ==(Object o) → bool
This equality override works for _RxImpl instances and the internal values.
