var file = new File('some_video.mp4');

handleRequest(HttpRequest request) async {
  // Parse the header
  var header = new RangeHeader.parse(request.headers.value(HttpHeaders.rangeHeader));

  // Optimize/canonicalize it
  var items = RangeHeader.foldItems(header.items);
  header = new RangeHeader(items);

  // Get info
  header.items;
  header.rangeUnit;
  header.items.forEach((item) => item.toContentRange(400));

  // Serve the file
  var transformer = new RangeHeaderTransformer(header, 'video/mp4', await file.length());
  await file.openRead().cast<List<int>>().transform(transformer).pipe(request.response);
