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

canUpdate → bool

no setter, inherited

firstRebuild ↔ bool

getter/setter pair, inherited

hashCode → int

The hash code for this object.

sentToStream ↔ bool

getter/setter pair, inherited

stream → Stream<T>

string → String

Same as toString() but using a getter.

Methods

addError(Object error, [StackTrace? stackTrace]) → void

inherited

addListener(GetStream<T> rxGetx) → void

This is an internal method. Subscribe to changes on the inner stream.

inherited

bindStream(Stream<T> stream) → void

Binds an existing Stream<T> to this Rx

inherited

call([T? v]) → T

updates the value to null and adds it to the Stream. Even with null-safety coming, is still an important feature to support, as call() doesn't accept null values. For instance, InputDecoration.errorText has to be null to not show the "error state".

inherited

close() → void

Closes the subscriptions for this Rx, releasing the resources.

inherited

listen(void onData(T), {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T>

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

refresh() → void

Makes a direct update of value adding it to the Stream useful when you make use of Rx for custom Types to referesh your UI.

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(void 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).

inherited

Operators

operator ==(Object o) → bool

This equality override works for _RxImpl instances and the internal values.
