in Dart, what is the best way to know if a class has been defined?

in my program, I wish to different behavior depending on whether a class has been defined.

if one had undefined as in javascript, something like this:

  var i = (NewClass == undefined) ? new OldClass() : new NewClass();

since Dart is compiled, can something like this be done?

seems the best answer is to search for the class NewClass using the string "NewClass". see Instantiate a class from a string

I'm not sure what you actually want to express.

In Dart you can't dynamically define classes (at least not yet)
therefore such an if makes no sense.
