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.

Example:

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

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

Implementation

bool isScheme(String scheme);
