toString method

  1. @override
String toString()
override

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 contents = [
    'totalTokenCount=$totalTokenCount',
    'textCount=$textCount',
    'imageCount=$imageCount',
    'videoDurationSeconds=$videoDurationSeconds',
    'audioDurationSeconds=$audioDurationSeconds',
  ].join(',');
  return 'UsageMetadata($contents)';
}
