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 'AudioUrlResult(success: $success, audioUrl: ${audioUrl?.isNotEmpty == true ? '${audioUrl!.substring(0, 50)}...' : 'null'}, '
'title: $title, artist: $artist, videoId: $videoId, audioQuality: $audioQuality, '
'message: $message, error: $error)';
}
