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.
Similar to Obx, but manages a local state.
Pass the initial data in constructor.
Useful for simple local states, like toggles, visibility, themes,
button states, etc.
Sample:
ObxValue((data) => Switch(
value: data.value,
onChanged: (flag) => data.value = flag,
),
false.obs,
),
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.
