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() {
final contents = [
'name=$name',
'displayName=$displayName',
'mimeType=$mimeType',
'sizeBytes=$sizeBytes',
if (sha256Hash != null) 'sha256Hash=$sha256Hash',
'uri=$uri',
'downloadUri=$downloadUri',
'state=$state',
'source=$source',
].join(',');
return 'File($contents)';
}
