10. Implementing DI in KMP with Koin

To integrate Koin for Dependency Injection in a Kotlin Multiplatform Project (KMP), you need to add the core dependency to the commonMain source set in your shared module's build.gradle.kts file. Here’s the setup:

…/shared/build.gradle.kts

kotlin {
    ...
    sourceSets {
        commonMain.dependencies {
            ...
            // koin dependencies
            implementation(project.dependencies.platform(libs.koin.bom))
            implementation(libs.koin.core)
        }
    }
}

Why Only koin.core?

1. Platform Independence: koin.core works across all platforms, making it perfect for the commonMain source set.
2. Essential Features: It provides all necessary DI features like module definitions, singletons, and factories.
3. Lean Shared Codebase: Keeping the shared codebase lean avoids unnecessary platform-specific dependencies.

By adding only koin.core, you ensure a robust and platform-independent DI setup for your shared code in KMP.
