aws_polly_api could really use an example

I'm not able to figure out how to play the returned audiostream directly. Am I supposed to save it as an mp3 file on local storage first? What's a good way to deal with this.

There's one other dart library for Polly aws_polly, which works in two steps, providing a URL to the audio stream directly from Polly, which is easy to feed to any audio player. Is this possible with aws_polly_api?
