Properties

hashCode → int

The hash code for this object.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

value → Object?

The inner value, may contain Json objects in maps or lists

no setter

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson({bool shallow = false}) → Object?

Returns a serializable Json value. if shallow, it will not serialize inner Json values

toJsonShallow() → Object?

Returns the inner json value

toString() → String

A string representation of this object.

inherited

when<T>({required T map(Map<String, Json>), required T list(List<Json>), required T number(num), required T boolean(bool), required T str(String), required T none(Null)}) → T

Executes the given callback when [this.value is of the type parameter.

Operators

operator ==(Object other) → bool

The equality operator.

override

Static Properties

graphQLType → GraphQLJsonType

The GraphQLType associated with Json

no setter

Static Methods

fromJsonChecked(Object? value, {String? getter, bool isRoot = true}) → Result<Json, String>

Creates a Json from a valid Json value. Similar to fromJson but does not throw when value could not be coerced into a Json, it returns an error message instead

Constants

null_ → const JsonNone

A null Json value
