This is not a bug in mobx, but depending on your code, build_runner may not work. In my experience, I've had no problems using the libraries mentioned above. I can't help you without reproducible source code.

See below to help you resolve the issue.

For anyone coming across this issue who does not get the - relatively sparse - docs about adjusting the build order, add this to your build.yaml file:

global_options:
  json_serializable:json_serializable:
    runs_before:
      - mobx_codegen:mobx_generator

Replace the reference to json_serialization with the package and builder you are using.

Same issue here, on our case, it puts "InvalidType" instead of "AppLifecycleState" or "Size".

Same issue here, with type AppLocalizations from the package I10n import 'package:flutter_gen/gen_l10n/app_localizations.dart';
