update method
Send the updated object to the server.
Will only send the dirty (modified) data and not the entire object
The object should hold an objectId in order to update it
Implementation
@override
Future<ParseResponse> update({dynamic context}) async {
if (objectId == null) {
return await signUp();
} else {
final ParseResponse response = await super.update();
if (response.success) {
await _onResponseSuccess();
}
return response;
}
}
