A special GraphQLType that indicates that an input value may be valid against one or more possibleTypes.

All provided types must be GraphQLObjectTypes.

description → String: A description of this type, which, while optional, can be very useful in tools like GraphiQL.
no setteroverride
hashCode → int: The hash code for this object.
no setteroverride
name → String: The name of this type.
final
possibleTypes → List<GraphQLObjectType>: A list of all types that conform to this union.
final
runtimeType → Type: A representation of the runtime type of the object.

coerceToInputObject() → GraphQLType<Map<String, dynamic>, Map<String, dynamic>>: Turns this type into one suitable for being provided as an input to a GraphQLObjectField.
override
convert(Object? value) → Map<String, dynamic>?: Attempts to cast a dynamic value into a Serialized instance.
inherited
deserialize(Map<String, dynamic> serialized) → Map<String, dynamic>: Deserializes a serialized value.
override
list() → GraphQLListType<Map<String, dynamic>, Map<String, dynamic>>: inherited
nonNullable() → GraphQLType<Map<String, dynamic>, Map<String, dynamic>>: 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
serialize(Map<String, dynamic> value) → Map<String, dynamic>: Serializes an arbitrary input value.
override
toString() → String: A string representation of this object.
inherited
validate(String key, covariant Map<String, dynamic> input) → ValidationResult<Map<String, dynamic>>: Performs type coercion against an input value, and returns a list of errors if the validation was unsuccessful.
