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();
  if (latestVersion == null) {
    buf.writeln('Could not determine latest version.');
  } else {
    buf.writeln('Current version:  $currentVersion');
    buf.writeln('Latest version:   $latestVersion');
    if (updateAvailable) {
      buf.writeln('');
      buf.writeln('A newer version is available!');
    } else {
      buf.writeln('');
      buf.writeln('CLI is up to date.');
    }
  }
  if (message.isNotEmpty && latestVersion == null) {
    buf.writeln(message);
  }
  return buf.toString();
}
