PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh ./bin/configs/*.yaml
  ./bin/utils/export_docs_generators.sh
  

  (For Windows users, please run the script in Git BASH)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.6.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

This looks wrong, do you have a stacktrace for the error?

abstract interface class Exception {
  factory Exception([var message]) => _Exception(message);
}

[kewur]

it's a compiler error for when using json serializer with these arguments

-g dart-dio --additional-properties=serializationLibrary=json_serializable

this is the generated exception

@JsonSerializable(
  checked: true,
  createToJson: true,
  disallowUnrecognizedKeys: false,
  explicitToJson: true,
)
class Exception {
  /// Returns a new [Exception] instance.
  Exception({

     this.targetSite,

     this.message,

     this.data,

     this.innerException,

     this.helpLink,

     this.source_,

     this.hResult,

     this.stackTrace,
  });

You seem to have a custom Exception class/element in your schema that conflicts with the default Exception class from Dart.
Please rename the element in your schema or follow https://openapi-generator.tech/docs/customization/#name-mapping to map it if you can't change your schema.

interesting, the swashbuckle .net generator does indeed create an Exception definition.

Perhaps the OpenApi exception should be renamed instead, as this seems to be picking up the C# Exception implementation. I'm suprised im the first one to run into this issue.

either way, the change isn't valid you're correct. closing.

This is the Dart SDK Exception class, we have no way of renaming it.

[kewur]

I was thinking about using the ApiException, since that's also used throughout the code, except for this instance.

@wing328 This is no valid change. Please close the PR.
