Demystifying Dart's Reflection: When to Use Code Generation for Powerful Flutter Features

Dart's lack of full runtime reflection in Flutter often frustrates developers used to languages like C#, limiting dynamic tool building. This post will clarify why Flutter restricts reflection (tree-shaking benefits), explain the `dart:mirrors` library's role, and most importantly, provide practical strategies for achieving similar powerful capabilities through compile-time code generation and annotations, with real-world examples.
