Overview
ioc_container is a lightweight, flexible, and high-performance dependency injection (DI) and service location library designed for Dart and Flutter applications. It enables clean separation of concerns by managing object creation and dependencies, reducing boilerplate and improving testability. The library supports hierarchical containers, lazy instantiation, and easy registration of singletons and factories. Ideal for scalable apps requiring structured dependency management without heavy frameworks.
