Right now, you have to reference Icons statically by calling the proper getter on the Icons class. It would be useful to be able to reference icons by their string key as well.

One use case: sharing code between AngularDart and Flutter apps. Let's say you have a Dart function that returns the material icon that should be used for some argument. What do you return? For web, you're required to specify the string key of the icon but Flutter doesn't let you do that.
