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/utils/export_docs_generators.sh
  

  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*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master (5.3.0), 6.0.x
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Can you create a sample config in bin/configs and add the sample to the samples.dart-2.13 in the pom.xml. Then we can run it automatically in CI.

@kuhnroyal I've added the sample config, a pom.xml and added that pom to the project pom.xml. I'm not sure how the _tests sample gets generated though (e.g. samples/openapi3/client/petstore/dart-dio-next/petstore_client_lib_fake_tests)

[kuhnroyal]

Those are written by hand. Probably don't add those for now.

[kuhnroyal]

Nice!

Hi @josh-burton,

I have question related to dioImport, I'm creating a custom template for my project, based on dart-dio-next with small change, but when config the templateDir in config.yaml then I got the empty value like import ''; instead of import 'package:dio/dio.dart'

I have checked by removing the templateDir then I can see the expected result import 'package:dio/dio.dart'

config.yaml:

generatorName: dart-dio-next
outputDir: ../api_provider
inputSpec: openapi.json
templateDir: src/main/resources/dart/libraries/dio  # my problem is here
typeMappings:
  Client: "ModelClient"
  File: "ModelFile"
  EnumClass: "ModelEnumClass"
additionalProperties:
  hideGenerationTimestamp: "true"
  dioLibrary: dio
  clientName: api_provider
  pubVersion: 1.0.0
  pubName: api_provider
  pubLibrary: api_provider

And this is command I used to run the generator:

openapi-generator-cli generate --config \"./openapi_config.yaml\" --skip-validate-spec 

in node environment with package:

    "@openapitools/openapi-generator-cli": "^2.4.12",

Could you advice how to I correct it?
