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() {
  String str = '\n---↓↓↓ RESULT ↓↓↓---\nEVENT:\n$event\nNODES:\n';
  nodes?.forEach((treeId, e) {
    str += '$treeId : $e\n';
  });
  str += '\n---↑↑↑ RESULT ↑↑↑---\n';
  return str;
}
