Properties

astNode → TypeDefinitionNode?
If this was parsed from an ast, the node in that ast
no setterinherited
attachments → GraphQLAttachments
Other custom values that may modify the execution, validation or introspection for this element
no setterinherited
description → String?
A description of this type, which, while optional, can be very useful in tools like GraphiQL.
no setterinherited
extra → GraphQLTypeDefinitionExtra<ScalarTypeDefinitionNode, ScalarTypeExtensionNode>
no setteroverride
generic → GenericHelp<Value>
Utility for working with the Value Generic type
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isNonNullable → bool
true when the type can not be null
no setterinherited
isNullable → bool
true when the type can be null
no setterinherited
name → String
The name of this type.
no setteroverride
printableName → String
The name of this type with defaults for GraphQLWrapperType. Can be used as a name of another GraphQL type, useful for composing names for generic types, for example.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

Methods

coerceToInputObject() → GraphQLType<Value, Serialized>
Turns this type into one suitable for being provided as an input to a GraphQLObjectField.
override
deserialize(SerdeCtx serdeCtx, Serialized serialized) → Value
Deserializes a serialized value.
inherited
list() → GraphQLListType<Value?, Serialized>
Returns a GraphQLListType with the inner type set to this
inherited
nonNull() → GraphQLNonNullType<Value, Serialized>
Creates a non-nullable type that represents this type, and enforces that a field of this type is present in input data.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
nullable() → GraphQLType<Value, Serialized>
Returns a nullable type that represents this type. If the type is isNullable returns itself without changes.
inherited
serialize(Value value) → Serialized
Serializes a value.
inherited
serializeSafe(Object? value, {bool nested = true}) → Serialized
inherited
toString() → String
A string representation of this object.
inherited
validate(String key, Object? input) → ValidationResult<Serialized>
Performs type coercion against an input value, and returns a list of errors if the validation was unsuccessful.
inherited
when<O>({required O enum_(GraphQLEnumType<Value>), required O scalar(GraphQLScalarType<Value, Serialized>), required O object(GraphQLObjectType<Value>), required O input(GraphQLInputObjectType<Value>), required O union(GraphQLUnionType<Value>), required O list(GraphQLListType), required O nonNullable(GraphQLNonNullType<Value, Serialized>)}) → O
Executes any of the provided function with this as argument. The function executed depends on the type of this
inherited
whenMaybe<O>({O enum_(GraphQLEnumType<Value>)?, O scalar(GraphQLScalarType<Value, Serialized>)?, O object(GraphQLObjectType<Value>)?, O input(GraphQLInputObjectType<Value>)?, O union(GraphQLUnionType<Value>)?, O list(GraphQLListType)?, O nonNullable(GraphQLNonNullType<Value, Serialized>)?, required O orElse(GraphQLType)}) → O
Similar to when, but with optional arguments and a required default case orElse, which is executed when none of the provided functions match this
inherited
whenOrNull<O>({O? enum_(GraphQLEnumType<Value>)?, O? scalar(GraphQLScalarType<Value, Serialized>)?, O? object(GraphQLObjectType<Value>)?, O? input(GraphQLInputObjectType<Value>)?, O? union(GraphQLUnionType<Value>)?, O? list(GraphQLListType)?, O? nonNullable(GraphQLNonNullType<Value, Serialized>)?}) → O?
Similar to when, but with optional arguments. Returns null when none of the provided functions match this
inherited

Operators

operator ==(Object other) → bool
The equality operator.
