couldCanonicalize method
Without accessing the filesystem, returns whether or not passing url
to
canonicalize could possibly return canonicalUrl
.
This is expected to be very efficient, and subclasses are allowed to
return false positives if it would be inefficient to determine whether
url
would actually resolve to canonicalUrl
. Subclasses are not allowed
to return false negatives.
Implementation
FutureOr<bool> couldCanonicalize(Uri url, Uri canonicalUrl) => true;
