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() => 'O11yPushoverConfig[notifierConfig=$notifierConfig, device=$device, expire=$expire, html=$html, httpConfig=$httpConfig, message=$message, monospace=$monospace, priority=$priority, retry=$retry, sound=$sound, title=$title, token=$token, tokenFile=$tokenFile, ttl=$ttl, url=$url, urlTitle=$urlTitle, userKey=$userKey, userKeyFile=$userKeyFile]';
