• Local Authentication Feature using RoomDB with local validations
• User Session Handling
• Add Car with different Makes and Models

App built with Kotlin and Android Jetpack Components.

• Single activity with multiple fragments is used with MVVM architecture.
• Jetpack libraries such as ViewModel, DataBinding, Navigation Component, LiveData.
• Used RoomDB for local caching.
• Used Hilt for Dependency Injection.
• Coroutines and Flow for asynchronous.

• MVVM Architecture (Model - View - ViewModel)
• Repository Pattern
• It follows the Google's official architecture guidance.
• The overall architecture of the app is composed of three layers; the UI layer, the data layer and the viewModel. Each layer has dedicated components and they have each different responsibilities.
• Each layer follows unidirectional event/data flow; the UI layer emits user events to the data layer and the data in the viewModel is observed by the UI Layer.
• The data layer is designed to work independently from other layers and must be pure, which means it doesn't have any dependencies on the other layers.
• With this loosely coupled architecture, you can increase the reusability of components and scalability of your app.
