RockitoWatcher<T extends OkitoController> function
RockitoWatcher is the easiest and the most lightweight way to observe controller changes outside of OkitoBuilder using Rockitos.
It differs from RockitoBuilder in one way, RockitoBuilder creates a StatefulWidget to observe changes, so that you can display your widget, but RockitoWatcher doesn't create any widget, it is just a callback function that gives you access to the state and watch state changes of your OkitoController.
Example
// This type is required.
RockitoWatcher<CounterController>(
(controller) {
print('Count is changed to ${controller.count}');
},
)
Implementation
// ignore: non_constant_identifier_names
Function RockitoWatcher<T extends OkitoController>(
/// The function that called whenever controller state changes.
/// (controller) => /* Your code here */
WatcherCallback<T> callback, {
T? inject,
}) {
if (inject != null) Okito.inject(inject);
final watch = Okito.use<T>();
return controllerXviewStream.watch(
watch,
() => callback(watch),
);
}
