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 '{${this.url}, ${this.expiry}, ${this.created}, ${this.title}, ${this.body}, ${this.imgUrl}, ${this.deliveryId}, ${this.messageId}, ${this.opened}}';
}
