toString method
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() => 'orderId: $orderId,'
'\npurchaseToken: $purchaseToken,'
'\npayload: $payload,'
'\npackageName: $packageName,'
'\npurchaseState: $purchaseState,'
'\npurchaseTime: $purchaseTime,'
'\nproductId: $productId,'
'\noriginalJson: $originalJson,'
'\ndataSignature: $dataSignature';
