toString method

@override String toString([ String prefix = '' ])

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([String prefix = '']) {
  var buffer = StringBuffer();
  buffer.writeln("${prefix}$extnId: ${isCritical ? "critical" : ""}");
  buffer.writeln('${prefix}\t$extnValue');
  return buffer.toString();
}
