No support for preview attribute of submission about draw

[TheNightmanCodeth]

I'm accessing the preview property like so:
post.data["preview"]["images"][0]["source"]["url"]
just swap out the 0 for the resolution you want. 0 is full resolution, up to (i think) 4 which is the smallest size. However, the preview property is sometimes not available. Some subreddits can choose to have the feature disabled by default so if you're using an unauthorized client, or your user doesn't have a certain setting enabled on their profile an exception will be thrown.

Thanks for the suggestion @Heasummn! I'll take a look and get that added for you.

In the meantime, I'm fairly certain you should be able to pull this value out of the data property for the submission (although I'm not certain which key it would be under).

Sorry for the delay on this. I've published version 0.4.0 which includes a preview property in Submission. It looks like the Dart 2.0 release broke a couple of dependencies that haven't updated their SDK constraints, so it looks like dartdoc won't generate the documentation. Take a look here for the signature.
