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() => 'Sheet[id=$id, provider=$provider, accountId=$accountId, ownerUserId=$ownerUserId, name=$name, description=$description, data=$data, rowCount=$rowCount, columnCount=$columnCount, sheetCount=$sheetCount, isPublic=$isPublic, isReadOnly=$isReadOnly, fileSize=$fileSize, lastAccessedAt=$lastAccessedAt, createdAt=$createdAt, updatedAt=$updatedAt]';
