What were you expecting to happen?

As the title say, i want to know how to listen the end event of current task in the plugin. I am developing a plugin that needs to delete some dir when the current task end. But i can not find a way to do this besides to add an event listener in the task like the blow code

function pluginTest() {
  return src(path)
    .pipe(newPlugin())
    .pipe(dest('dist'))
    .on('end', () => {})
}

What i want is the plugin can know the end time of the task, so i can do the thing in the plugin, so i can use the plugin like this:

function pluginTest() {
  return src(path)
    .pipe(newPlugin())
    .pipe(dest('dist'))
}
