It's a mixin that provides a set of methods that can be used to observe the lifecycle of an instance.
Example usage:
class MyController with LifecycleObserver {
final state = UseState('initial');
@override
void onInitialized() {
print('MyController has been initialized');
}
@override
void onDidUpdate(ReactterState? state) {
print("$state has been changed");
}
}
// MyController has been initialized
final myController = Reactter.create(() => MyController());
// state has been changed
myController.state.value = "value changed";
