Hilt is a dependency injection library for Android that simplifies the process of providing dependencies in an application. It is built on top of Dagger, another popular dependency injection framework, and aims to reduce boilerplate code while improving the ease of use. Hilt integrates seamlessly with the Android lifecycle, making it easier for developers to manage dependencies in their apps. By using Hilt, developers can annotate their classes to define how dependencies are provided and scoped. This allows for cleaner code and better organization, as dependencies are automatically managed and injected where needed. Overall, Hilt enhances the development experience for Android applications.
