toString method

@override String toString()

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() {
  final styleString = style != null
      ? '{ ${style!.entries.map((e) => '${e.key}: "${e.value}"').join(', ')} }'
      : 'null';

  return '''
  {
    ${format != null ? 'format: "$format",' : ''}
    ${style != null ? 'style: $styleString' : ''}
  }
  ''';
}
