Observable.onError处理程序不会阻止异常终止应用程序

我对调试这些错误没有结果感到厌倦 任何人都知道错???！？!!？！

当添加的Stream发出正常事件时，它工作正常，但是在发出错误时，它由onErorr方法处理，并且如您在StackTrace中看到的那样，发生了奇怪的错误。

test("Testing the Stream", () async {

 final _categoriesInfosSubject = new PublishSubject<String>();
 var errorThrown = false;

 Observable<String>  categories$ = _categoriesInfosSubject.stream;
 categories$.listen(any, onError: (err){ print("ErrorHappened"); errorThrown = true;});

 await _categoriesInfosSubject.addStream(
  Observable.error(Error()),
 );
 await Future.delayed(Duration(seconds: 2), (){});
 expect(errorThrown , true);

});
