Objects

GraphQL objects allow you to specify a type with a set of fields or properties. Objects can only be outputs in a resolver. Each field can be of any output type.

GraphQL Specification

The Query, Mutation and Subscription types in the schema are specified using GraphQL objects.

final type = objectType(
  'ObjectTypeName',
  fields: [],
);
  • With code generation
@GraphQLObject()
@JsonSerializable()
class Model {
  final String stringField;
  final int intField;
  final List<Model>? optionalModels;

  const Model({
    required this.stringField,
    required this.intField,
    required this.optionalModels,
  });
}

@Query
Future<Model> getModel(Ctx ctx) {

}

This would generate graphql_api.schema.dart


Interfaces​

GraphQL Specification

  • inheritFrom

The inheritFrom function in GraphQLObjectType receives an Interface and assigns it's argument as
a super type, now the Object will implement the Interface passed as parameter.
