GraphQLNonNullType<Value, Serialized> class

A special GraphQLType that indicates that input values should both be non-null, and be valid when asserted against another type, named ofType.

Properties

description → String
A description of this type, which, while optional, can be very useful in tools like GraphiQL.
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
ofType → GraphQLType<Value, Serialized>
The wrapped type
final
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() → GraphQLNonNullType<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.
override
field<P>(String name, {String? deprecationReason, String? description, FutureOr<Value> resolve(P parent, Ctx<P> ctx)?, FutureOr<Stream<Value>> subscribe(Object? parent, Ctx ctx)?, Iterable<GraphQLFieldInput<Object?, Object?>> inputs = const [], FieldDefinitionNode? astNode, GraphQLAttachments attachments = const []}) → GraphQLObjectField<Value, Serialized, P>
Utility for creating an GraphQLObjectField with type == this
inputField(String name, {String? description, Value? defaultValue, String? deprecationReason, InputValueDefinitionNode? astNode, GraphQLAttachments attachments = const []}) → GraphQLFieldInput<Value, Serialized>
Shorthand for generating a GraphQLFieldInput.
list() → GraphQLListType<Value, Serialized>
Returns a GraphQLListType with the inner type set to this
override
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.
override
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.
override
serializeSafe(Object? value, {bool nested = true}) → Serialized
inherited
toString() → String
A string representation of this object.
override
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.
override
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.
