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() {
return 'Plan{id: $id, productId: $productId, status: $status, '
'name: $name, description: $description, '
'quantitySupported: $quantitySupported, createTime: $createTime, '
'updateTime: $updateTime, links: $links}';
}
