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 label = StringBuffer();
  if (control == true) label.write('ctrl+');
  if (alt == true) label.write('alt+');
  if (shift == true) label.write('shift+');
  if (meta == true) label.write('meta+');
  label.write(key.debugName ?? key.keyLabel);
  return label.toString();
}
