It will even become possible to dynamically evaluate code that was not yet specified literally in the source code. An example of this would be calling a method whose name was provided as an argument because it is looked up in the database table.

Getting ready

The part of your code that uses reflection should have the following import code:

import 'dart:mirrors';

How to do it...

        embr.strength += 5;
