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() {
  StringBuffer buffer = StringBuffer();
  buffer.writeln('----------------------------------------------------');
  buffer.writeln('selectedItem: ${selectedItem.toLongString()}');
  (elements != null && elements.isNotEmpty) ?? buffer.writeln('items: ');
  elements?.forEach((item) {
    buffer.writeln('item: ${item.toLongString()}');
  });
  (favoriteElements != null && favoriteElements.isNotEmpty) ?? buffer.writeln('favoriteItems: ');
  favoriteElements?.forEach((item) {
    buffer.writeln('favoriteItem: ${item.toLongString()}');
  });
  buffer.writeln('----------------------------------------------------');
  return buffer.toString();
}
