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 details = StringBuffer();

  var firststate = true;
  for (final statePath in _leafPaths) {
    if (!firststate) {
      details.write('\n  and ');
    }
    firststate = false;
    var firstpart = true;
    for (final path in statePath.path) {
      if (!firstpart) {
        details.write('->');
      }
      firstpart = false;
      details.write(path.stateType.toString());
    }
  }
  return details.toString();
}
