toString method Null safety

  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() {
  return 'BookInfo(title: $title, subtitle: $subtitle authors: $authors, publisher: $publisher, publishedDate: $publishedDate, rawPublishedDate: $rawPublishedDate, description: $description, industryIdentifiers: $industryIdentifiers, pageCount: $pageCount, categories: $categories, averageRating: $averageRating, ratingsCount: $ratingsCount, maturityRating: $maturityRating, contentVersion: $contentVersion, imageLinks: $imageLinks, language: $language, previewLink: $previewLink, infoLink: $infoLink, canonicalVolumeLink: $canonicalVolumeLink)';
}
