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() => '(purchaseId: $purchaseId, '
'store: $store, '
'vendorProductId: $vendorProductId, '
'vendorTransactionId: $vendorTransactionId, '
'purchasedAt: $purchasedAt, '
'isSandbox: $isSandbox, '
'isRefund: $isRefund, '
'isConsumable: $isConsumable)';
