Hilt Dependency Injection in Android with Kotlin from Udemy

Dependency Injection is now an indispensable component of Android development. All well built, large projects use it to make development easier and more practical.

Hilt is the next generation dependency injection framework from Google. It's built on top of Dagger and simplifies DI greatly. Android development has been steadily relied upon Dependency Injection, and Hilt is now the fastest and simplest way to implement it in your projects.

This course will

take you from a complete beginner in the technology
explain in detail the theoretical aspects of Hilt injection
exhaustively go through all the components that make Hilt such a successful library
implement it in a practical application

After this course you will have the knowledge and experience to use Hilt in all your app development projects, and will allow your apps to grow and expand seamlessly.

We will learn about:

Modules
Constructor injection
Field injection
Method injection
Components
Qualifiers
Standard qualifiers
ViewModel injection
Unit testing

We will build everything in Kotlin.

We cover a lot of ground in this course, and we will implement the concepts practically so that you get not only theoretical knowledge but practical experience as well. Whether you start with zero experience in dependency injection or you already know a little bit about it through dagger, this course will show you how to use it with Hilt.
