A dynamic class is basically one that can be modified at runtime. One of the main uses of this feature is when extending the Proxy class.

A couple of good examples:

Here You can find basic info : http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/statements.html#dynamic

Dynamic class allow You to add additional dynamic params to object in run-time .

For example : Sprite isnt dynamic , so You cannot do thing like :

var sprite:Sprite = new Sprite ();
sprite["value"] = 10; // this will throw ReferenceError

But MovieClip is dynamic instance that allow You to add dynamic params :

var mclip:MovieClip = new MovieClip();
mclip["value"] = 10;

To make class instance dynamic , You have to add 'dynamic' key word to declaration :

public dynamic class MyClass { ...
