Dependency injection in Unity doesn’t have to be heavy or slow. Reflex is a lightweight, high-performance DI framework designed specifically for Unity projects. It supports scoped and hierarchical containers, AOT compatibility (including IL2CPP and WebGL), and dramatically outperforms Zenject and VContainer in both speed and GC allocations. In this video, we’ll walk through setting up Reflex step by step, explore singleton, scoped, and transient lifetimes, and show how to inject dependencies cleanly using fields, properties, methods, and runtime resolution.
