singleWhere method

  1. @override
AsObservableFuture<T> singleWhere(
  1. bool test(
    1. T element
  2. {T orElse(

    Finds the single element in this stream matching test.

    Like lastWhere, except that it is an error if more than one matching element occurs in this stream.


    AsObservableFuture<T> singleWhere(bool test(T element), {T orElse()}) =>
        AsObservableFuture<T>(_stream.singleWhere(test, orElse: orElse));
