This is an application that consumes the API of Blockchain and display a linear chart of the bitcoin transactions per second on a given range & other stats. The graph is made with whimsical.

This project is monolithic(for now) and has only one screen. However, all inner packages are well organized in order to be scalable and modularized in the following days. It uses MVVM as Software Design Patter and is using Jetpack Compose for the UI.

• :core:functional-programming contains the Either sealed class & some helper methods. Either is the "wrapper" for handle Either an Error or a Success structure.
• :core:network contains some middlewares & extensions for execute safe retrofit calls (I write 3 articles about it -> Create a safe retrofit calls extension part I, II, & III)
• :core:network/middlewares middlewares are going to act as a firewall before executing any retrofit call. Only if all the middlewares are supplied then the retrofit call is allowed to be executed.
• :utils has utilities interfaces like a ResourceProvider & ConnectivityUtils, who's implementations will be in the app module.
• :features:home Home is our only feature (for now), it has it's data sources, mappers & repositories interfaces for prepare the data and send it to the HomeViewModel.
• :ui:components: contains our composables.
• :tests unit tests for repository, datasources, mappers, etc. I also write articles about this. Unit Tests & Instrumented Tests
• :app module contains our HiltApplication in charge to create the app DI graph and the interface implementations from our libraries.
