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() {
  return 'PurchaseData{ '
      'productId: $productId,'
      'productType: $productType,'
      'productTitle: $productTitle,'
      'price: $price,'
      'priceCurrency: $priceCurrency,'
      'purchaseDate: $purchaseDate,'
      'purchaseId: $purchaseId'
      '}';
}
