tryParse method

Uri tryParse (String uri, [ int start = 0, int end ])

Creates a new Uri object by parsing a URI string.

If start and end are provided, they must specify a valid substring of uri, and only the substring from start to end is parsed as a URI. The uri must not be null.

Returns null if the uri string is not valid as a URI or URI reference.


static Uri tryParse(String uri, [int start = 0, int end]) {
  // TODO: Optimize to avoid throwing-and-recatching.
  try {
    return parse(uri, start, end);
  } on FormatException {
    return null;
