Built With 🛠

Some of the popular libraries and MVVM clean architecture used with Room database as a source

  • Kotlin - First class and official programming language for Android development.

  • Coroutines - Threads on steroids for Kotlin

  • Flow - A cold asynchronous data stream that sequentially emits values and completes normally or with an exception.
  • StateFlow - A live data replacement

  • Android JetPack - Collection of libraries that help you design robust, testable, and maintainable apps.

    • Paging3 - Load and display small chunks of data at a time.
    • ViewModel - Stores UI-related data that isn't destroyed on UI changes.
    • ViewBinding - A robust replacement for findViewById, kotlin sytnhetics and DataBinding
    • Navigation Components - Navigate fragments as never easier before
    • SavedStateHandle - A handle to saved state passed down to androidx.lifecycle.ViewModel.
    • Room - Persistence library provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
    • Biometrics - Authenticate with biometrics or device credentials, and perform cryptographic operations.
    • Security - Safely manage keys and encrypt files and sharedpreferences.
    • Start-up - Implement a straightforward, performant way to initialize components at app startup such as our crash reporting library Crashy.
  • Material Components for Android - Modular and customizable Material Design UI components for Android.
  • Dependency Injection -

    • Hilt-Dagger - Standard library to incorporate Dagger dependency injection into an Android application.
    • Hilt-ViewModel - DI for injecting ViewModel.
