The Dart core libraries can be compiled into a snapshot file that allows fast loading of the libraries. Most standard distributions of the main Dart VM have a prebuilt snapshot for the core libraries that is loaded at runtime. Object snapshots Dart uses snapshots to serialize messages that it passes between

Simula introduced important concepts that are today an essential part of object-oriented programming, such as class and object, inheritance, and dynamic binding. [10] The object-oriented Simula programming language was used mainly by researchers involved with physical modelling, such as models to study and improve the movement of ships and ...
The object enacts whichever behavior it implements. [2] Dynamic dispatch contrasts with static dispatch, in which the implementation of a polymorphic operation is selected at compile time. The purpose of dynamic dispatch is to defer the selection of an appropriate implementation until the run time type of a parameter (or multiple parameters) is ...
An object's methods act in essence like functions, and a method may accept objects as parameters and produce objects as return values. Objects often carry added run-time overhead compared to pure functions, however, and added boilerplate code for defining and instantiating an object and its method(s).
Finally, introduce a class named Object with members to control its visibility (using a VisibilityDelegate), movability (using an UpdateDelegate), and solidity (using a CollisionDelegate). This class has methods which delegate to its members, e.g. update() simply calls a method on the UpdateDelegate :
