Generator.dio causes error Error: 'NullThrownError' isn't a type.

[isaac-merkos]

Description of the bug

When I run dart run build_runner build --delete-conflicting-outputs on a project with this class

// Openapi Generator last run: : 2024-12-10T12:54:07.988426
import 'package:openapi_generator_annotations/openapi_generator_annotations.dart';

@Openapi(
    additionalProperties: AdditionalProperties(useEnumExtension: true, pubName: 'api_client'),
    inputSpec: RemoteSpec(path: 'http://localhost:3000/openapi.json'),
    generatorName: Generator.dio,
    skipIfSpecIsUnchanged: false,
    outputDirectory: 'api/api_client')
class Client {}

I get this error

[SEVERE] openapi_generator on lib/client.dart:

Steps to reproduce

I am not sure exactly how to reproduce it but every dependency is up to date

Minimal openapi specification

https://petstore3.swagger.io/api/v3/openapi.json

Annotation used

// Openapi Generator last run: : 2024-12-10T12:54:07.988426
import 'package:openapi_generator_annotations/openapi_generator_annotations.dart';

@openapi(
additionalProperties: AdditionalProperties(useEnumExtension: true, pubName: 'api_client'),
inputSpec: RemoteSpec(path: 'http://localhost:3000/openapi.json'),
generatorName: Generator.dio,
skipIfSpecIsUnchanged: false,
outputDirectory: 'api/api_client')
class Client {}

Expected behavior

I expected it to generate a client
