toString$ method
Returns a string representation of this Uri. The representation and normalization of a URI depends on the scheme.
- The resulting string can be safely used with {@link Uri.parse}.
- The resulting string shall not be used for display purposes.
Note that the implementation will encode aggressive which often leads to unexpected,
 but not incorrect, results. For instance, colons are encoded to %3A which might be unexpected
 in file-uri. Also & and = will be encoded which might be unexpected for http-uris. For stability
 reasons this cannot be changed anymore. If you suffer from too aggressive encoding you should use
 the skipEncoding-argument: uri.toString(true).
@param skipEncoding Do not percentage-encode the result, defaults to false. Note that
	the # and ? characters occurring in the path will always be encoded.
 @returns A string representation of this Uri.
Implementation
_i2.String toString$([_i2.bool? skipEncoding]) => _i5.callMethod(
      this,
      'toString',
      [skipEncoding ?? _i6.undefined],
    );
