Common mistakes when working with Koin?

When working with Koin in Android development, developers may encounter several common mistakes that can lead to confusion or bugs in their applications. Understanding these pitfalls can help in achieving a smoother integration of Koin into your projects.

1. Incorrect Scope Definition

One common mistake is not defining the scopes correctly, which can lead to unexpected behavior during dependency injection.

2. Forgetting to Start Koin

Another common issue is forgetting to start Koin in the application class.

3. Overusing Single Instances

Overusing single instances without proper scoping can lead to memory leaks and unexpected application states.

4. Poorly Defined Modules

Failing to define modules clearly can lead to confusion and make it hard to manage dependencies.

5. Not Using Constructor Injection

Relying heavily on field injection instead of constructor injection can lead to tightly coupled code, making it harder to test.

Example of Correct Koin Setup

// Start Koin in Application class class MyApp : Application() { override fun onCreate() { super.onCreate() startKoin { // declare used Android context androidContext(this@MyApp) // declare modules modules(myModule) } } } // Define a module val myModule = module { single { MyRepository() } factory { MyViewModel(get()) } }
