toString method

@override String toString({ bool doubleQuotes = true, })

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString({bool doubleQuotes = true}) {
  final quotationMark = (doubleQuotes) ? '"' : '\'';
  final encoding = (this.encoding != null)
      ? ' encoding=$quotationMark${this.encoding}$quotationMark'
      : '';
  final standalone = (this.standalone != null)
      ? ' standalone=$quotationMark${(this.standalone!) ? 'yes' : 'no'}'
          '$quotationMark'
      : '';
  return '<?xml version=$quotationMark$version'
      '$quotationMark$encoding$standalone ?>';
}
