toString method

  1. @override
String toString()
override

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 List<String> pairs = <String>[];
  final Map<String, dynamic> dataMap = getDataMap();
  final List<String> sortedKeys = dataMap.keys.toList()..sort();
  for (final String key in sortedKeys) {
    pairs.add('$key: ${dataMap[key]}');
  }
  return '${objectRuntimeType(this, 'SemanticsEvent')}(${pairs.join(', ')})';
}
