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() =>
'SubscriptionPurchase(purchaseId: $purchaseId, invoiceId: $invoiceId, orderId: $orderId, purchaseType: $purchaseType, description: $description, purchaseTime: $purchaseTime, price: $price, amountLabel: $amountLabel, currency: $currency, status: $status, developerPayload: $developerPayload, sandbox: $sandbox, productId: $productId, expirationDate: $expirationDate, gracePeriodEnabled: $gracePeriodEnabled)';
