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() {
  if (this == critical) return 'critical';
  if (this == high) return 'high';
  if (this == normal) return 'normal';
  if (this == low) return 'low';
  if (this == background) return 'background';
  return 'custom($value)';
}
