fetchAllTypes function

List<GraphQLType?> fetchAllTypes(
  1. GraphQLSchema schema,
  2. List<GraphQLType?> specifiedTypes
)

Every type reachable from schema, plus specifiedTypes.

The three root operation types are walked transitively, so a type only mentioned deep inside a field still turns up. This is what introspection answers __schema { types } with.

Implementation

List<GraphQLType?> fetchAllTypes(
  GraphQLSchema schema,
  List<GraphQLType?> specifiedTypes,
) {
  var data = <GraphQLType?>{}
    ..add(schema.queryType)
    ..addAll(specifiedTypes);

  if (schema.mutationType != null) {
    data.add(schema.mutationType);
  }

  if (schema.subscriptionType != null) {
    data.add(schema.subscriptionType);
  }

  return CollectTypes(data).types.toList();
}
