Directive @extends status

[Robert-Scub]

Hello!

Thank you for this superb API.

My backend is generating a schema that contains this directive declaration:

directive @extends on OBJECT | INTERFACE

I need to remove it or else it break Flutter code generation.

line 1, column 266 of .: 'extends' can't be used as an identifier because it's a keyword.

Thanks!

I came across this too, most likely it should be discussed in the gql repository

Yes, please open an issue in the gql repo, as this is the place where the parsing of the schema is implemented.

Edit: forgot that "transfer issue" exists, so I did it myself ;)

[knaeckeKami]

could you try out the gql_code_builder status of #335 (by using dependency_overrides) to check if this solves this issue?

  gql_code_builder:
    git:
      path: codegen/gql_code_builder
      url: https://github.com/gql-dart/gql.git
      ref: bugfix/espace-references
        

If not, I would be grateful for a minimal graphql schema that triggers this bug

I tried to check this out, but I got an error in the build:
