Kotlin View Models

View models in Kotlin, especially within the Android architecture, play a crucial role in managing UI-related data in a lifecycle-conscious way. They act as a communication bridge between the UI controller (like an Activity or Fragment) and the data source of the application, ensuring that data survives configuration changes such as screen rotations.

By storing UI-related data in a ViewModel, Android developers can create more robust and efficient applications. The ViewModel class is designed to store and manage UI-related data in a way that is aware of the lifecycle of the activities and fragments, preventing memory leaks and keeping the app's UI data valid and available throughout the lifecycle of its components. Kotlin's language features, such as null safety and extension functions, further simplify the development of ViewModels, making the code more concise and readable.
