Why Generics Beat dynamic
Keep type safety while staying reusable.
The Reuse Problem
You often want one piece of code to work with many types. Writing a separate version for each type is tedious, so Dart gives you generics. 🎯
The dynamic Escape Hatch
One quick fix is to type everything as dynamic, which accepts any value. It feels flexible, but it quietly throws away all of Dart's type checking.
