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. https://www.youtube.com/watch?v=5XQkeWy_5Ko

I referenced from the getx issue https://github.com/jonataslaw/getx/issues/2966

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

hi sir, please fix the futurize method as onEmpty will not be triggered in any condition.
