Add a way to generate classes for some types in the schema about ferry HOT 6 CLOSED

The way do to this with ferry is to use a fragment

fragment BasePokemonInfo on Pokemon {
    id
    name
    type
}

and then reuse this fragment

query Pokemon0($id: ID!) {
  pokemon(id: $id) {
    ...BasePokemonInfo
  }
}

# lib/graphql/query.pokemon_1.graphql

query Pokemon1($id: ID!) {
  pokemon(id: $id) {
     ...BasePokemonInfo
     weight
  }
}

This will generate an abstract class GBasePokemonInfo and the types on both queries will implement this fragment.

I think so. If not, please file a bug ;)

Does that fit your usecase?

It's a little different than what you described, but I think it's safer this way.
If we generated the full type and you used that in your code, your code might break if an additional field is added to the schema.

Thank you for the suggestion!
Would theGBasePokemonInfoFragment still be generated if it is not used in any query?

I should fit my use case yes, thank you! I still need to try it out

from ferry.

I created a fragment (unused anywhere, but it could be used):

# lib/graphql/fragment.pokemon.graphql

fragment PokemonFragment on Pokemon {
  id
  name
  type
}

The generator did create a GPokemonFragmentData class that I can use

// lib/main.dart
void main() {
  final pokemon = GPokemonFragmentData(
    (pokemon) => pokemon
      ..id = 'id'
      ..name = 'name'
      ..type = 'type',
  );
}

Thank you @knaeckeKami, it did fit my use case and is probably safer than what I was asking initially!

Closing the issue
