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() {
  var s = '';
  if (KeyMod.contains(mod, KeyMod.ctrl)) s += 'ctrl+';
  if (KeyMod.contains(mod, KeyMod.alt)) s += 'alt+';
  if (KeyMod.contains(mod, KeyMod.shift)) s += 'shift+';

  final str = MouseButton.toName(button);
  if (str.isEmpty) {
    s += 'unknown';
  } else if (str != 'none') {
    s += str;
  }
  if (s.isNotEmpty && !s.endsWith('+')) {
    s += ' ';
  }
  s += '($x,$y)';
  return s;
}
