Methods

getKind() → EntityKind<Object>
Returns Kind of this entity.
inherited
instanceCast(Object? value) → T
Casts the value to T or throws an error.
instanceIsCorrectType(Object? value) → bool
Tells whether the argument is an instance of the wanted Dart type.
instanceIsDefaultValue(Object? value) → bool
Tells whether the argument is a value returned by newInstance.
instanceIsValid(Object? value) → bool
A shorthand for checking validity with instanceValidate.
instanceValidate(ValidateContext context, Object? value) → void
Checks that the type is correct and then validates constraints with instanceValidateConstraints.
instanceValidateConstraints(ValidateContext context, T value) → void
Validates that the argument matches constraints (minimum length, etc.).
instanceValidateOrThrow(Object? value) → void
A shorthand for calling instanceValidate with the context ValidateContext.throwing().
jsonTreeDecode(Object? value, {JsonDecodingContext? context}) → T
Converts the argument (a JSON tree) into an instance of T.
jsonTreeEncode(T instance, {JsonEncodingContext? context}) → Object?
Converts the argument into a JSON tree.
newInstance() → T
Returns new default value.
newList(int length, {bool growable = false, bool reactive = true}) → List<T>
Returns a new list of this kind, which is guaranteed some properties.
newListFrom(Iterable<T> iterable, {bool growable = true, bool reactive = true}) → List<T>
A method similar to the list constructor List.from.
newListGenerate(int length, T function(int i), {bool growable = false, bool reactive = true}) → List<T>
A method similar to the list constructor List.generate.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
protobufNewInstance() → Object?
Constructs package:protobuf GeneratedMessage field value (e.g. bool, Int64, GeneratedMessage).
protobufTreeDecode(Object? value, {ProtobufDecodingContext? context}) → T
Converts the argument (a Protocol Buffers tree) into an instance of T.
protobufTreeEncode(T instance, {ProtobufEncodingContext? context}) → Object
Converts the argument into a Protocol Buffers tree.
randomExample({RandomExampleContext? context}) → T
Generates a random example.
randomExampleList(int n, {RandomExampleContext? context}) → List<T>
Generates a list of N random examples (with randomExample).
toNonNullable() → Kind<T>
Returns a non-nullable version of this kind.
toNullable() → NullableKind<T>
Returns a nullable version of this kind.
toString() → String
A string representation of this object.

Operators

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