But once projects become larger, problems start appearing: difficult testing tightly coupled code duplicated instances poor scalability difficult maintenance I personally experienced this while working on scalable Flutter applications with: authentication APIs Firebase local database push notifications repositories multiple modules Managing dependencies manually quickly became messy. That’s where Dependency Injection became extremely useful. In this article, I’ll explain: what Dependency Injection actually is why Flutter apps need it how it improves architecture singleton vs factory service locators get_it usage repo...
