Notify If the Stream Continued Pass a Pipe or Instead Ended at Pipe - Node - Gulp - JS

Question

Update - The more I dig into this... the more I think it has to do with node.

I using gulp-newer and gulp-notify, which includes node-notifier. When I run a tasks that doesn't produce any new files, because newer doesn't see any changes and jumps out of the task. I would like to have a notification saying Done - no new files. All it does now is end without notification.

Quick code Example:

gulp.task('copy', function(){
        return gulp.src('/app')
            .pipe(newer('/dist')) 
           - insert code to notify if all the files are the same or if stream ends before next pipe...
            .pipe(gulp.dest('/dist'))
            .pipe(notify({message: 'Copy task done', onLast: true}));
    });

Here is an example of code I've tried -

.pipe($.newer(path.distBase).on('end',function(){ $.nodeNotifier.notify({message:'No Files'})}))

The issue being that newer always ends. I need to know if the stream ends or continues on, I think.
