Properties

final Type runtimeType #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

Operators

bool operator ==(Tuple<T1, T2> other) #

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

docs inherited from Object
bool operator ==(Tuple<T1, T2> other) {
  return other != null && item1 == other.item1 && item2 == other.item2;
}

Methods

int hashCode() #

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

docs inherited from Object
int hashCode() => Util.getHashCode([item1, item2]);

noSuchMethod(String name, List args) #

inherited from Object

noSuchMethod is invoked when users invoke a non-existant method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod. If noSuchMethod returns a value, that value becomes the result of the original invocation.

The default behavior of noSuchMethod is to throw a noSuchMethodError.

external Dynamic noSuchMethod(String name, List args);

const Object() #

inherited from Object

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

const Object();

toJson() #

Dynamic toJson() => { 'item1' : item1, 'item2' : item2 };

String toString() #

Returns a string representation of this object.

docs inherited from Object
String toString() => "{item1: $item1, item2: $item2}";

const Tuple(T1 item1, T2 item2) #

const Tuple(this.item1, this.item2);
