Futurize with statemixin does not run properly in the onEmpty state

[nugrahazzz]

Describe the bug
I used statemixin and futurize but to trigger onEmpty it doesn't work properly. For Widgets that appear in a successful position, onLoading and onError are running properly but onEmpty is not running properly even with the help of change(GetStatus.empty)... Under what conditions is onEmpty triggered? Let's say I have a List of Model, does onEmpty refer to the length of lists = 0 (.isEmpty)?

Futurize (default) method from rx_notifier.dart

Future<void> futurize( Future<T> Function() body, { T? initialData, String? errorMessage, bool useEmpty = true, }) async { final Future<T> Function() compute = body; _value ??= initialData; await compute().then( (T newValue) { if ((newValue == null || newValue._isEmpty()) && useEmpty) { status = GetStatus<T>.loading(); } else { status = GetStatus<T>.success(newValue); } refresh(); }, onError: (Object err) { status = GetStatus<T>.error(errorMessage ?? err.toString()); refresh(); }, ); }

Change to

Future<void> futurize( Future<T> Function() body, { T? initialData, String? errorMessage, }) async { final Future<T> Function() compute = body; _value ??= initialData; await compute().then( (T newValue) { if (newValue == null) { status = GetStatus<T>.loading(); } else { if( newValue!._isEmpty()){ status = GetStatus<T>.empty(); } else { status = GetStatus<T>.success(newValue); } } refresh(); }, onError: (Object err) { status = GetStatus<T>.error(errorMessage ?? err.toString()); refresh(); }, ); }

To Reproduce
I just followed the futurize tutorial on the youtube channel and realized that onEmpty will not be triggered under any circumstances.

I referenced from the getx issue jonataslaw/getx#2966

Expected behavior
onEmpty will be triggered when the data is retrieved and the data is empty
