openapi: 3.0.0

          description: OK
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Path'

components:
  schemas:

    Points:
      properties:
        x:
          items:
            type: float
          type: array
        y:
          items:
            type: float
          type: array
      required:
      - x
      - y
      type: object

    Path:
      allOf:
        - $ref: '#/components/schemas/Points'    
      properties:
        id:
          type: integer
        meta:
          default: ''
          type: string
      required:
        - id
        - meta
      type: object

gives:

class Path {
...
  List<String> x;     // Should be List<int>
  List<String> y;

Reproduces with:

java -jar openapi-generator-cli-7.13.0.jar generate -i problem.yaml -g dart -o ./_swagger --additional-properties=pubLibrary=flutter_common_openapi,pubName=flutter_common_openapi

can you try enabling the rule REFACTOR_ALLOF_WITH_PROPERTIES_ONLY in openapi normalizer?

java -jar openapi-generator-cli-7.13.0.jar generate -i problem.yaml -g dart -o ./_swagger --additional-properties=pubLibrary=flutter_common_openapi,pubName=flutter_common_openapi --openapi-normalizer REFACTOR_ALLOF_WITH_PROPERTIES_ONLY=true

... makes no difference.

Also the following is the same:

    Path:
      allOf:
        - $ref: '#/components/schemas/Points'
        - type: object
          properties:
            id:
              type: integer
            meta:
              default: ''
              type: string
          required:
          - id
          - meta

        x:
          items:
            type: float
          type: array

that's not correct

float should be defined as the following according to the spec

        x:
          items:
            type: number
            format: float
          type: array

Makes sense. Thank you.
Would be nice if spec errors like this could cause a warning.
