Code new Uri.fromString(String uri) #

Code const Uri.fromComponents([String scheme = "", String userInfo = "", String domain = "", int port = 0, String path = "", String query = "", String fragment = ""]) #

Methods
Code bool hasAuthority() #
bool hasAuthority() {

}
Code bool isAbsolute() #
Returns true if the URI is absolute.
