Dio generator error: Expected an identifier

[jdk-21]

Description of the bug

I'm trying to generate the Jellyfin openapi spec with dio. The http-generator seems to work fine. The normal code generation works, but when the build_runner runs inside the generated api, it fails with following errors:

[INFO] Precompiling build script... completed, took 3.3s
[INFO] Building new asset graph completed, took 486ms
[INFO] Checking for unexpected pre-existing outputs. completed, took 0ms
[INFO] Generating SDK summary completed, took 2.5s
[SEVERE] built_value_generator:built_value on lib/src/model/transcoding_profile.dart:

This builder requires Dart inputs without syntax errors.
However, package:openapi/src/model/transcoding_profile.dart (or an existing part) contains the following errors.
transcoding_profile.dart:96:35: Expected an identifier.
transcoding_profile.dart:98:25: Expected an identifier.

Try fixing the errors and re-running the build.

[INFO] Running build completed, took 17.0s
[INFO] Caching finalized dependency graph completed, took 260ms
[SEVERE] Failed after 17.2s

transcoding_profile.dart:

@BuiltValueHook(initializeBuilder: true)
  static void _defaults(TranscodingProfileBuilder b) => b
      ..estimateContentLength = false
      ..enableMpegtsM2TsMode = false
      ..transcodeSeekInfo = const ._(TranscodeSeekInfo.auto) // Error
      ..copyTimestamps = false
      ..context = const ._(EncodingContext.streaming) // Error
      ..enableSubtitlesInManifest = false
      ..minSegments = 0
      ..segmentLength = 0
      ..breakOnNonKeyFrames = false;

I tried generating with the cli and the annotation:

openapi-generator generate -i ../jellyfin-openapi-stable.json  -g dart-dio

@Openapi(
    additionalProperties:
        DioProperties(pubName: 'jellyfin_api', pubAuthor: 'Johnny dep'),
    inputSpecFile: 'jellyfin-openapi-stable.json',
    generatorName: Generator.dio,
    outputDirectory: 'api/jellyfin_api',
    alwaysRun: true)
class Example {
}

Steps to reproduce

Download the OpenAPI spec from https://api.jellyfin.org Run the code generation via CLI or Annotations

Hi, I know this has been a while but here is something that might help. Basically, you either update the spec or update the code.

Since this library is a wrapper around the openapi-generator, you might want to open an issue there.
