Although Anko is no longer officially maintained, it remains a reference for having simplified Android development with Kotlin in its early days. Today, the community uses more modern extensions that are compatible with Jetpack.

You can take advantage of extensions for views, such as simplifying the management of RecyclerView or ViewBinding .
Libraries for DI and state management
Koin : A lightweight dependency injection solution , iraq telegram data written in Kotlin, ideal for modern Android projects.
startKoin {
modules(appModule)
}

StateFlow and LiveData: Both tools are essential for managing state in Kotlin applications, especially in combination with Jetpack Compose.
Other useful resources
Room : Local database library, fully compatible with Kotlin.
Retrofit + Kotlin Serialization: To work with REST APIs, simplifying the conversion of JSON data into Kotlin objects.
The tools and libraries in the Kotlin ecosystem are designed to take full advantage of the language’s features, promoting more efficient and robust development. Whether you’re designing declarative interfaces with Jetpack Compose or managing complex states with Coroutines, these tools ensure an optimal, modern development experience .

Practical design examples
Kotlin's versatility allows you to design interfaces and structure code in a clear, concise, and efficient way. Below are some practical examples that show how to take advantage of the language's features to build robust and functional solutions.

1. Using data classes to model UI
Data classes are ideal for representing user interface data or state. Their ability to automatically generate methods like toString , equals , and hashCode makes data handling in Kotlin simple.

Example:

data class UserProfile(val name: String, val email: String, val avatarUrl: String?)

fun displayUserProfile(user: UserProfile) {
println("Name: ${user.name}")
println("Email: ${user.email}")
user.avatarUrl?.let { println("Avatar: $it") } ?: println("No avatar available")

This approach allows you to structure data cleanly and easily manipulate it in different parts of the interface.
