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 result = runtimeType.toString();

  if (path case var path?) {
    if (result.contains(',')) {
      result += ', file: $path';
    }

    result += ' file: $path';
  }

  if (line case var line?) {
    if (result.contains(',')) {
      result += ', line: $line';
    } else {
      result += ' line: $line';
    }
  }

  if (message case var message?) {
    return '$result: $message';
  }

  return result;
}
