isRootRelative method
Returns true
if path
is a root-relative path and false
if it's not.
URLs that start with /
are known as "root-relative", since they're
relative to the root of the current URL. Since root-relative paths are still
absolute in every other sense, isAbsolute will return true for them. They
can be detected using isRootRelative.
No POSIX and Windows paths are root-relative.
Implementation
bool isRootRelative(String path) => p.context.isRootRelative(path);
