Android + MVVM + Coroutines Flow + Koin + Testing :heart:

This is an example of an Android App who uses coroutines flow to retrieve a list of https://jsonplaceholder.typicode.com/posts but retrieve the data one per one and be added to the RecyclerView.

V2

• Add screen to see the detail of the post (you need to tap an item on the RecyclerView)
• Update Gradle Version to 4.0.1 (you need Android Studio 4.0.1 or upper)
• Update dependencies

V3 (working)

• Change Layouts for Compose :)
