canonicalMediaType method
Returns the canonical version of this media type, if it is known.
This is useful to find the name and file extension of a known media type, or to get the
canonical media type from an alias. For example, application/x-cbz
is an alias of the
canonical application/vnd.comicbook+zip
.
Non-significant parameters are also discarded.
Implementation
Future<MediaType> canonicalMediaType() async =>
(await ofSingleHint(mediaType: toString())) ?? this;
