Observable<T>.never constructor

Observable<T>.never()

Returns a non-terminating observable sequence, which can be used to denote an infinite duration.

The never operator is one with very specific and limited behavior. These are useful for testing purposes, and sometimes also for combining with other Observables or as parameters to operators that expect other Observables as parameters.

Example

new Observable.never().listen(print); // Neither prints nor terminates

Implementation

factory Observable.never() => Observable<T>(NeverStream<T>());
