 ### Fixed
 * Fixed an issue where connections to Atlas App Services would fail on Android with a certificate expiration error. (Issue [#1430](https://github.com/realm/realm-dart/issues/1430))
+* Fixed an issue with the generator where having multiple generated classes in the same file would result in multiple `// ignore_for_file: type=lint` lines being added, which itself was generating a lint warning. (Issue [#1412](https://github.com/realm/realm-dart/issues/1412))
 * Errors encountered while reapplying local changes for client reset recovery on partition-based sync Realms would result in the client reset attempt not being recorded, possibly resulting in an endless loop of attempting and failing to automatically recover the client reset. Flexible sync and errors from the server after completing the local recovery were handled correctly. (Core 13.24.0)
 * During a client reset with recovery when recovering a move or set operation on a `List` that operated on indices that were not also added in the recovery, links to an object which had been deleted by another client while offline would be recreated by the recovering client. But the objects of these links would only have the primary key populated and all other fields would be default values. Now, instead of creating these zombie objects, the lists being recovered skip such deleted links. (Core 13.24.0)
 * During a client reset recovery a Set of objects could be missing items, or an exception could be thrown that prevents recovery ex: "Requested index 1 calling get() on set 'source.collection' when max is 0". (Core 13.24.0)
