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 parent = super
      .toString()
      .joinWithValues(['blur'], actionSeparator: paramKeyValueSeparator);
  if (_region != null) {
    if (_region is Faces) {
      return parent.joinWithValues([_region],
          actionSeparator:
              paramKeyValueSeparator).joinWithValues([_strength]);
    }
    return parent +
        '_region'.joinWithValues([_strength]).joinWithValues([_region],
            actionSeparator: paramSeparator);
  }
  return parent.joinWithValues([_strength]);
}
