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 buffer = StringBuffer('TemplateSyntaxError');

  if (path case var path?) {
    buffer
      ..write(", file '")
      ..write(path)
      ..write("'");
  }

  if (line case var line?) {
    buffer
      ..write(', line ')
      ..write(line);
  }

  if (message case var message?) {
    buffer
      ..write(': ')
      ..write(message);
  }

  return buffer.toString();
}
