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() {
  return ''.joinWithValues([
    ((_height != null) ? 'h_$_height' : null),
    ((_width != null) ? 'w_$_width' : null),
    ((_x != null) ? 'x_$_x' : null),
    ((_y != null) ? 'y_$_y' : null)
  ], separator: paramSeparator, actionSeparator: '');
}
