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() => 'Attachment[actions=$actions, assetUrl=$assetUrl, authorIcon=$authorIcon, authorLink=$authorLink, authorName=$authorName, color=$color, custom=$custom, fallback=$fallback, fields=$fields, footer=$footer, footerIcon=$footerIcon, giphy=$giphy, imageUrl=$imageUrl, ogScrapeUrl=$ogScrapeUrl, originalHeight=$originalHeight, originalWidth=$originalWidth, pretext=$pretext, text=$text, thumbUrl=$thumbUrl, title=$title, titleLink=$titleLink, type=$type]';
