Flutter 3: property 'destDir' is missing an input or output annotation

[tudor07]

Can't build Android version on Flutter 3

* What went wrong:
Some problems were found with the configuration of task ':flutter_locker:extractDebugProto' (type 'ProtobufExtract').
  - In plugin 'com.google.protobuf' type 'com.google.protobuf.gradle.ProtobufExtract' property 'destDir' is missing an input or output annotation.

    Reason: A property without annotation isn't considered during up-to-date checking.

    Possible solutions:
      1. Add an input or output annotation.
      2. Mark it as @Internal.

    Please refer to https://docs.gradle.org/7.4.2/userguide/validation_problems.html#missing_annotation for more details about this problem.

I'm having an issue with the new version 2.0.4. 2.0.3 works just fine, but 2.0.4 doesn't compile and gives an error with protobuf as well

Downgraded to 2.0.3 and its still working fine

This is weird, 2.0.4 works on my machine.

Anyway, the protobuf library that we use, often gives us some issues (as it is in your case). So our goal now is to completely replace protobuf, but for that you'll have to wait (hopefully a week or two). I'll keep you updated.

2.1.0 is out so protobuf should give you trouble anymores.
