Can you name popular libraries or tools for dependency injection in applications?

In Android, the following libraries and tools are popular for Dependency Injection:

• Dagger 2 — a static DI framework widely used due to its high performance and annotation support.
• Hilt — a wrapper over Dagger that simplifies DI setup in Android applications.
• Koin — a lightweight DI framework in Kotlin that does not require code generation.
• Butter Knife — although mainly for view binding, it is sometimes used together with DI.

In practice, Dagger 2 or Hilt are most often used for large projects, while Koin is preferred for simpler and faster solutions.
