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 mods = [
    if (ctrl) 'ctrl',
    if (alt) 'alt',
    if (shift) 'shift',
  ].join('+');
  final label = key?.name ?? char ?? '';
  return mods.isEmpty ? 'Key($label)' : 'Key($mods+$label)';
}
