isScheme method Null safety

bool isScheme (
  1. String scheme

Whether the scheme of this Uri is scheme.

The scheme should be the same as the one returned by Uri.scheme, but doesn't have to be case-normalized to lower-case characters.


var uri = Uri.parse("");
print(uri.isScheme("HTTP"));  // Prints true.

An empty scheme string matches a URI with no scheme (one where hasScheme returns false).


bool isScheme(String scheme);
