Warning
According the standard of React, the key should always be supplied directly to the elements in the array. In Transfer, the keys should be set on the elements included in dataSource array. By default, key property is used as an unique identifier.
If there's no key in your data, you should use rowKey to specify the key that will be used for uniquely identify each element.
// eg. your primary key is `uid`
return <Transfer rowKey={record => record.uid} />;
