Fetch (read fully) content body from a resource identified by reference.

Depending on the API the reference can be a relative path, an absolute URL, a key, or other identifier relevant on a context of an API.

Throws an ApiException if fetching fails. Implementations like HTTP fetcher may also throw other status codes than codes for success as exceptions.

  final file = await _fileFromUri(reference);
  try {
    return FileContent(
      contentType: _contentType,
      encoding: _encoding,
      contentLength: await file.length(),
  } on Exception catch (e) {
    throw ClientException.failed(reference, e);
