GraphQL class

A Dart implementation of a GraphQL server.

Constructors

GraphQL(GraphQLSchema schema, {bool introspect = true, FutureOr<T> defaultFieldResolver<T>(T, String?, Map<String, dynamic>)?, List<GraphQLType> customTypes = const <GraphQLType>[]})

Properties

customTypes → List<GraphQLType>
Any custom types to include in introspection information.
final
defaultFieldResolver → (FutureOr<T> Function<T>(T, String?, Map<String, dynamic>)?)
An optional callback that can be used to resolve fields from objects that are not Maps, when the related field has no resolver.
final
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
