[pigeon] Analyzer warnings in generated ProxyApi code #183945
Description
Several of our packages using proxy APIs have pub.dev score deductions for warnings in the generated code:
- https://pub.dev/packages/camera_android_camerax/score
- https://pub.dev/packages/webview_flutter_android/score
- https://pub.dev/packages/camera_android_camerax/score
They fall into two buckets:
- Generating a codec variable even if it's not used. Example:
WARNING: The value of the field '_pigeonVar_codecSecTrust' isn't used. lib/src/common/web_kit.g.dart:9636:47
- Unnecessary casts to
Object?when exacting args. Example:WARNING: Unnecessary cast. lib/src/common/web_kit.g.dart:2581:37 ╷ 2581 │ final Object? arg_body = (args[2] as Object?);
We try to keep Pigeon-generated code passing the analyzer, generally; we should see why our existing Pigeon tests didn't catch these. Probably we don't have test pigeon definition files that generate the necessary conditions?
