toString method

@override @useResult 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
@useResult
String toString() {
  final buffer = StringBuffer();
  buffer.write(config.openTag);
  buffer.write(' -');
  buffer.write(sourceStartLine);
  if (outputCounts) {
    buffer.write(',');
    buffer.write(sourceCount);
  }
  buffer.write(' +');
  buffer.write(targetStartLine);
  if (outputCounts) {
    buffer.write(',');
    buffer.write(targetCount);
  }
  buffer.write(' ');
  buffer.write(config.closeTag);
  final labelToApply = config.defaultLabel;
  if (labelToApply != null) {
    buffer.write(' ');
    buffer.write(labelToApply);
  }
  buffer.writeln();
  return buffer.toString();
}
