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() {
  final buf = StringBuffer();
  buf.writeln('--- a/$oldPath');
  buf.writeln('+++ b/$path');
  for (final hunk in hunks) {
    buf.write(hunk);
  }
  return buf.toString();
}
