build_runner: ^1.7.1
json_serializable: ^3.2.3

i post the same issue in https://github.com/dart-lang/json_serializable/issues/551 too, because im not sure if this is json_serializable or build_runner related issue or not.

Please update your build_resolvers version (by doing a pub upgrade or flutter packages pub upgrade. This doesn't appear directly in your deps as it is a transitive dependency but it had a bug that surfaces under new sdks and needs to be updated to the latest.
