Insert Koin
summary
Koin is a Kotlin-first dependency injection library that uses a small DSL to declare single and factory bindings and to retrieve dependencies with get() or inject(), with named dependencies for disambiguation. It supports property and parameterized providers, nested contexts with explicit release for lifecycle-scoped components, direct Android ViewModel integration, and runtime validation with an optional dry-run graph walk for tests; teams report using it at scale with similar runtime performance to Dagger 2 but much less boilerplate.
