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() => 'O11yEmailConfig[notifierConfig=$notifierConfig, authIdentity=$authIdentity, authPassword=$authPassword, authPasswordFile=$authPasswordFile, authSecret=$authSecret, authSecretFile=$authSecretFile, authUsername=$authUsername, forceImplicitTls=$forceImplicitTls, from=$from, headers=$headers, hello=$hello, html=$html, requireTls=$requireTls, smarthost=$smarthost, text=$text, threading=$threading, tlsConfig=$tlsConfig, to=$to]';
