Chapter 2. Advanced Techniques and Reflection

In this chapter, we will discuss the flexibility and reusability of your code with the help of advanced techniques in Dart. Generic programming is widely useful and is about making your code type-unaware. Using types and generics makes your code safer and allows you to detect bugs early. The debate over errors versus exceptions splits developers into two sides. Which side to choose? It doesn't matter if you know the secret of using both. Annotation is another advanced technique used to decorate existing classes at runtime to change their behavior. Annotations can help reduce the amount of boilerplate code to write your applications. And last but not least, we will open Pandora's box through Mirrors of reflection. In this chapter, we will cover the following topics:

Generics
Errors versus exceptions
Annotations
Reflection
