tryParse static method

Uri? tryParse(
  1. String uri, [
  2. int start = 0,
  3. 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.

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

Example:

final uri = Uri.tryParse(
    'https://dart.dev/guides/libraries/library-tour#utility-classes', 0,
    16);
print(uri); // https://dart.dev

var notUri = Uri.tryParse('::Not valid URI::');
print(notUri); // null

Implementation

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;
  }
}
