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 modifiers = <String>[];
  if (isCtrlPressed) modifiers.add('Ctrl');
  if (isAltPressed) modifiers.add('Alt');
  if (isShiftPressed) modifiers.add('Shift');
  if (isMetaPressed) modifiers.add('Meta');

  final modifierString =
      modifiers.isNotEmpty ? '${modifiers.join('+')}+' : '';

  if (code == KeyCode.char) {
    return 'KeyEvent($modifierString${char ?? 'null'})';
  }
  return 'KeyEvent($modifierString${code.name})';
}
