Methods

bool operator ==(other) #

inherited from Object

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.

bool operator ==(other) => identical(this, other);

int hashCode() #

inherited from Object

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.

external int hashCode();

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);

Type get runtimeType() #

inherited from Object

A representation of the runtime type of the object.

external Type get runtimeType;

String toString() #

inherited from Object

Returns a string representation of this object.

external String toString();
