Description

The problem occurred when dart-dio was generated using the OpenAPI 3.1.0 version of the definition file.
The reason is that when creating a GET API using the [Query / PATH] parameter, the import of the dependent class is no longer generated (JsonObject: built_value/json_object.dart).
In OpenAPI 3.0.3, there was no problem because the type of the target parameter is a primitive type. (ex. String)

openapi-generator version

{
  "$schema": "./node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,
  "generator-cli": {
    "version": "6.6.0"
  }
}

In addition to the above, similar problems occurred in 6.5.0 and 7.0.0-beta.

Generation Details

Steps to reproduce

1. Create the yaml or json shown in the example using Stoplight Studio
2. Run generate with the latest Docker container shown officially
3. Checking the contents of the generated file, import is missing (/lib/src/api/default_api.dart)

I could not find an Issue that is exactly the same.

Suggest a fix

I don't know why this is, but the file is generated without importing built_value/json_object.dart, causing a compile error.
