The implementation is based on https://github.com/dukefirehawk/angel/blob/master/packages/static/lib/src/virtual_directory.dart and adapted to Alfred.

Hey I just wanted to comment on this one - I am totally in favour of adding this feature, but I'm hesitant to drag in another dependency, especially as its something from angel that may not pan out - just being a small moving part of a larger whole.

I had a quick google shortly after you submitted it and it seems like returning a part of a file stream is pretty straightforward when you do an openread, and the spec according to mozilla is just to return a different status code, a header that says you can, and the portion of the file being returned.

So basically I want to have a go at building it out. I don't think it would take more than a dozen or so lines of code to implement unless I am totally misunderstanding the requirement - and I did have a look at the implementation from the framework which just looks enormous!

So anyway, I haven't forgotten it, I just haven't had a chance to circle back around to it yet.

I only added the angel3_range_header dependency which parses the range header. Apart from parsing the range header, my implemenation just returns a part of a file stream and sets some additional headers.

angel3_range_header is pretty small, it's just 6 files, well documented, well tested and standards-compliant. I don't see a reason not to use it. Even if it gets changed in an unwanted way, you could just fork it or copy the header parsing code over.
