Learn how to implement Koin as a dependency injection framework for Kotlin & Compose Multiplatform (KMP) in this tutorial.

• Dependency injection is like outsourcing the responsibility of baking a pizza. Just like we don’t care about how the pizza is made, we can use dependency injection to inject the required objects where needed in our code.
• Dependency injection framework allows us to simply specify the implementation we want to use for our app, making our code more maintainable and testable.
• By using coin, a dependency injection framework, in our Kotlin multiplatform project with Compose, we can easily inject types and make our code more flexible and maintainable.
• With the use of annotations and KSP, we can streamline the process of declaring dependencies and use them in our Compose code for our multiplatform project.

🍕 Introduction

Dependency injection is a crucial concept in software development, allowing developers to outsource the responsibility of object creation to a dependency framework. In this video, we will explore how to implement Koin, a dependency injection framework, in a Kotlin multiplatform project using Compose.

📦 Setting Up Koin

To start using Koin in a new Kotlin multiplatform project, you need to add the required dependencies and set up the project structure accordingly. Koin provides a DSL that allows you to define the types to be injected, making it compatible with almost any codebase.

🏗️ Using Koin for Dependency Injection

Once the setup is complete, you can declare your dependencies using Koin DSL and then use them in your app code. Koin provides various options for defining these dependencies, such as field injection, constructor injection, and more.

🔬 Declaring Dependencies with Koin DSL

Koin DSL allows you to declare the dependencies for your classes, specifying how they should be provided and utilized in your app. By using modules to define your types, you can ensure that the relevant instances are created and maintained as needed.

📱 Using Koin in Android and iOS

While using Koin in Android is straightforward with its integration using the Koin DSL, integrating Koin in iOS requires implementing the concept of multiplatform. You need to initialize Koin and provide the necessary modules for the iOS app to use.

🛠️ Using KSP for Koin

Kotlin Symbol Processing (KSP) is an essential part of using Koin in your Kotlin multiplatform project, as it helps in generating code based on annotations. By utilizing KSP, you can simplify the process of declaring dependencies and managing modules in your project.

🚀 Implementing Koin in Compose Code

Using Koin in Compose code involves injecting your dependencies using the Koin context and then utilizing them within your Composable functions. This integration allows for seamless dependency management within your multiplatform project.

🎤 Conclusion

By implementing Koin as a dependency injection framework in your Kotlin multiplatform project, you can streamline the process of managing dependencies and improve the maintainability of your codebase. Koin provides a robust solution for dependency management and is a valuable addition to any mobile app development endeavor.
