GetStream is the lightest and most performative way of working
with events at Dart. You sintaxe is like StreamController, but it works
with simple callbacks. In this way, every event calls only one function.
There is no buffering, to very low memory consumption.
event add will add a object to stream. addError will add a error
to stream. listen is a very light StreamSubscription interface.
Is possible take the last value with value property.
Unlike GetxController, which serves to control events on each of its pages,
GetxService is not automatically disposed (nor can be removed with
Get.delete()).
It is ideal for situations where, once started, that service will
remain in memory, such as Auth control for example. Only way to remove
it is Get.reset().
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.
This class is the foundation for all reactive (Rx) classes that makes Get
so powerful.
This interface is the contract that _RxImpl<T> uses in all it's
subclass.
GetX by default disposes unused controllers from memory,
Through different behaviors.
SmartManagement.full
SmartManagement.full is the default one. Dispose classes that are
not being used and were not set to be permanent. In the majority
of the cases you will want to keep this config untouched.
If you new to GetX then don't change this.
SmartManagement.onlyBuilders only controllers started in init:
or loaded into a Binding with Get.lazyPut() will be disposed. If you use
Get.put() or Get.putAsync() or any other approach, SmartManagement
will not have permissions to exclude this dependency. With the default
behavior, even widgets instantiated with "Get.put" will be removed,
unlike SmartManagement.onlyBuilders.
SmartManagement.keepFactoryJust like SmartManagement.full,
it will remove it's dependencies when it's not being used anymore.
However, it will keep their factory, which means it will recreate
the dependency if you need that instance again.
debounce is similar to interval, but sends the last value.
Useful for Anti DDos, every time the user stops typing for 1 second,
for instance.
When listener emits the last "value", when time hits,
it calls callback with the last "value" emitted.
Similar to ever, but takes a list of listeners, the condition
for the callback is common to all listeners,
and the callback is executed to each one of them. The Worker is
common to all, so worker.dispose() will cancel all streams.
Combine the Object.hashCode values of an arbitrary number of objects from
an Iterable into one value. This function will return the same value if
given null as if given an empty list.
Ignore all changes in listener during time (1 sec by default) or until
condition is met (can be a bool expression or a bool Function()),
It brings the 1st "value" since the period of time, so
if you click a counter button 3 times in 1 sec, it will show you "1"
(after 1 sec of the first press)
click counter 3 times in 1 sec, it will show you "4" (after 1 sec)
click counter 2 times in 1 sec, it will show you "7" (after 1 sec).
once() will execute only 1 time when condition is met and cancel
the subscription to the listener stream right after that.
condition defines when callback is called, and
can be a bool or a bool Function().
